Organic Definition and 432 Threads

I receieved an online organic chemistry prep tool from my college. It includes a couple of sections on alkanes. Do I really need start memorizing all these hydrocarbons for my organic chemistry class?

we ofen hear the terms organic, natural and chemical in the media. Organic and natural are usually used to imply that a product is "healthy" and/or "environmentally friendly" while chemical often implies negative implications for health and for the environment. In your opinion are these...

I'd like to work with solar cells made from organic material, and am currently leaning toward electrical engineering. I tried contacting Dr. Chen (mentioned here: http://investintaiwan.nat.gov.tw/en/news/200706/2007062001.html ), but have gotten no response. He is the only one at the Chiao...

Hi, I have here an alkyne reacting with C2H5NH2 in the presence of lithium and NH4Cl. Does the lithium catalyse the split of a proton from C2H5NH2 and also a Cl from the NH4Cl which then react with the alkyne across the triple bond?

After drawing the 8 alcohols with the formula C5H11OH, I'm asked to "Describe how they are formed and give two uses for this type of alcohol." The only example in my text for this is the hydration of an alkene which, at a glance, wouldn't make sense for 2,2-dimethyl 1 propanol. Is this one...

1)Give a chemical test that can be used to distinguis between separate samples of propanone and propanal. Give a suitable reagent for the test and describe what you would obsrve with propanone and with propanal. 2) Outline the reaction of propanone with the following reagents. Give the...

Can someone please tell me what the two bond between the two hyrdrogen and the carbons means?(the long black triangle, and the '''''')

If one has a mixture of borneol (standard bp: 210 C) and verbenone (standard bp: 227.5 C), would the mixture's boiling point theoretically be the average of the two (218.75 C), or is there something else I have to take into consideration (vapor pressure)? Thanks.

Is this even correct? A natural product (MW = 150 g/mol) distills with steam at a boiling temperature of 99 C at atmospheric pressure. The vapor pressure of water at 99 C is 733 mmHg. a. Calculate the weight of the natural product that codistills with each gram of water at 99 C...
