    Confused Isomers
AI Thread Summary
The discussion revolves around identifying the isomers of pentene. Participants clarify that in addition to pent-1-ene and pent-2-ene, which include both E and Z configurations, there are other isomers such as 3-methylbut-1-ene and cyclopentane. Further suggestions include 2-methylbut-1-ene, 2-methylbut-2-ene, ethylcyclopropane, dimethylcyclopropane, and methylcyclobutane. The conversation emphasizes the importance of varying both the position of the double bond and the carbon atom arrangements to explore all possible isomers. The thread is categorized under Homework and Coursework, indicating its educational context.

I have a question where I have to name the isomers of pentene. I understand how to do pent-1-ene and pent-2-ene, then I am stuck. Any prodding?
Thanks!

You've changed the positions of the double bond. Now try changing positions of the C-atoms. Pluck one out at the end and stick it back somewhere else.

Also, keep in mind that such threads belong in the Homework and Coursework forum.
 
Does the name 3-methyl-but-1-ene mean anything to you?
(Not forgetting cyclopentane, of course).

Right, 3-methylbut-1-ene is an isomer of pentene.

~But,
In addition to:
*pent-1-ene
*pent-2-ene (both E & Z :biggrin:)
*3-methylbut-1-ene
*cyclopentane

Consider:
*2-methylbut-1-ene
*2-methylbut-2-ene
*ethylcyclopropane
*dimethylcyclopropane
*methylcyclobutane

Thanks a lot even i got stuck after pent-1-ene, pent-2-ene and 2-methyl-but-1-ene.Again thanks for helping me to finish my homework.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
