Hey, I have a question which asks me to provide two examples of how organic chem can be used to improve existing products and therefore provide solutions to newly identified health or environment problems. One example is unleaded gasoline, instead of leaded. What are some others? I've...

What is an "organic functional group" ? What relation does it have towards pH ?

I have to take this exam in order to transfer my community college organic chem. I need to score in the 75th Percentile (I have no idea what that might be, maybe everyone gets 100s!) So, anyone take it? How'd you do? Anything unexpected? Advice? I have ordered a study guide for it and I'm...

Hi ppl, I have this question. I have the MF of a substance A : C7H7O2N. I have three pieces of info which should indicate a structural property of this substance:i) A reacts with sodium carbonate to give off CO2. I thought this might indicate an ionic structure? then ii) A will form a coloured...

Hi Does anyone know the reaction of an organic acid (carboxylic acid) with aluminium phosphate (AlPO_4)? If yes, please do let me know. Thanks and cheers Vivek

Hi What are the necessary and sufficient conditions for a compound to give a positive Haloform Test (Iodoform test for instance)? Is it necessary to have a CH_{3}CO- group or is it necessary to have a XCH_{2}- group where X is some group? Is the occurence of a CH_{3}CO- group a sufficient...

Hi, I want to know what happens when a mixture containing aldehyde(s) and ketone(s) is introduced to a mixture of formamide HCONH_2 and formic acid HCOOH. Do both aldehyde and ketone react? Or does only one react? Eagerly awaiting a response... Thanks and Cheers Vivek

Can anyone please name this compound: http://www.wwwebworld.co.uk/chem.JPG Thankyou

I have some properties of a substance and would like to know if they are considered to be high or low (the substance is ASA) - melting point: 136C - boiling point: 146C - solubility: 1g/100g If the solubility is considered to be low, then why is ASA good for the human body? i would think...

I know that a double bond has the two atoms closer to each other than a single bond. I have to build an organic acid model for chemistry and would like to know: - Is there a ratio between the lengths of C-C bonds to C=C bonds? - Are C-H bonds closer together than C-C bonds? - Are C=O bonds...

does any1 know where i can get a spider diagram for as level chemisry, like the reactions between different organic groups and suchlike thank you :biggrin: :smile:

organic chemistry help! how do i name a pentane with a double bond on one end and triple bond on the other end? pent-1-ene-4-yne? if an octane has a double bond on one carbon and a phenyl group on another carbon . which should i start with first, the phenyl or the double bond?

Well, did you? If so, why?

Hi I got a question regarding the following calculations: An organic substance consisting of Carbon, Hydrogen and Bromine and has a total mass of 1,55 grams. The carbon have a mass of 0,277 grams and the Hydrogen 0,046 grams. The mass of Bromine is 1,55 g - 0,277 g - 0,046 g = 1,23...

I have been searching like crazy for different and easier material on organic chemistry for higher level students on the net, but it's hard to find. I assume that there are knowledgeable participants on this part of the PF and I would like to ask if someone knows of a good link? :smile...

hey, if anyone is good with organic chem, could they please list some common and effective tests to distinguish between different organic compounds such as alkanols, acids and alkenes, etc.

Hi all I am doing this lab in my organic course right now, and I have a few questions. The phenol I am working on is pKa of p-chlorophenol. I obtained a UV spectrum of phenol in acid, phenol in base, phenol in buffer with higher pH and phenol in buffer with lower pH. 1)In the UV spectrum...

Isolating caffeine from tea leafs is an experiment in our lab. The manual asks us to determine the percent yield of caffeine by comparing the pure product of caffeine versus the original mass of the tea leafs. My question is, how valid is this method for finding percent yield? I do not...

Energetics of Organic Compunds!help The energy of interaction between a Mg cation and a Cl anion is -4.000 x 10 -19 J What is the distance in Angstroms between these two ions? Enter a numerical answer only, do not enter units. i tried and tried and can't get this...

well i have a really simple question about organic chemistry if someone could help me it wil be nice. Q. why is 2-bromocyclohexanal more easily hydrated as compared to cylohexanal. Q. Why are 3 Degree alcohols more basic the 1 degree alcohol. Q. Why we add finely divided platinium in...

what is organic substances?

Hi I have a few questions in organic chemistry. I would be very grateful if someone can answer them: 1. (cf Morrison & Boyd 6th ed page 523). "Strongly activating groups generally win out over deactivating or weakly activating groups." When the bromination of 3-hydroxybenzaldehyde...

Well i am having problem prepearing this alcohol from bromobenzene and 1-butene please help.This question is from Solomons organic chem.

I find it extremely tough to remember the correct mechanisms and apply them, there seems to be so many different structures etc. Can anyone offer any advice regarding learning organic chemistry? Are there any decent websites/material which lay out organic chemistry in a more accessible manner...

has anyone come across any website with good information on OLED technology. I'm not really looking for the technical details. What I?m interested in is a general overview of the technology. What it is advantage/disadvantages , applications, history. Stuff like that. i would really...

Survival Most books that teach the language of Mathematics, ignore our cognition’s abilities to understand and define the fundamental concepts of this language. Langauge is a tool that gives the cognition its ability to examine the object, the subject and the value of object/subject...

Hi everyone. I need help with some organic chemistry. When I see a reaction, how do I tell whether it is SN1, SN2, E1, or E2? Also, what is it about a nucleophile that makes it good or bad? Thanks in advance.

Hello, I came across this quetion... Complete and balance the following reactions: OH | CH3-CH2-CH2-CH-CH3 -> Now, I don't know if I've gone crazy or something, but what's supposed to happen to that? Its a simple alcohol (2-pentanol) standing there all...

What is the name of what looks like a benzene ring but one of the carbons is replaced with a nitrogen?

Hi there! This is my first post here, so a short introduction: my name is Rui Monteiro and i´m a Chemical Engineering student in Portugal, i´m 19. (btw, anyone from Portugal?) So, what brings me here: I came up with this Organic Chemistry Database (with a few inorganic compounds there too)...

As many of you know, I object to the reference of all intelligence, other than that of organic beings, as being "artificial". That is the point of this thread. Here are the definitions of the key-words, "intelligence" and "artifical": I have not included all definitions of "artificial"...
