It wants you to say that there is an alcohol and an alkene (double-bond). Functional groups govern the reactivity of organic molecules, since the C-C and C-H skeleton is pretty unreactive.

That was quick! Thanks for your help :cool:

I'm new to organic chemistry see

you'll get the subject soon enough- just be sure to remember all of those damn reactions and equations

Right sorry I have 1 last question:

draw diagrams of two isomers of C4H8 each of which are structural isomers of but-2-ene. Name each isomer.

Anyone? :confused:

i dunno how to draw on the computer so i'll have to explain it..sorry!

draw ur basic c=c group, and draw either
A) 2 methyl groups (CH3) attached to 2 different carbons, CIS/TRANS, OR;
b) 2 methyl groups (CH3) attached to the SAME carbon
C) an ethyl group (CH3CH2) attached to a carbon- making a 4 carbon chain (but-1-ene), with the c=c group at the end

COMPLICATED, but hope it gives u some guidance

ha! thanks rainjan, godess of chemistry! :cool:

I looked around a bit and i've come up with this:

I think that's about right, I hope :p: :cool:

'godess of chemistry' LOL

IT TOOK ME AGES TO GRASP SOME REACTIONS- believe me, there is worst to come- but yeah, ur pics are correct- except if you move one of the CH3 groups across the double bond and fiddle with the other then u get geometric isomers (cis/trans)- u'll have to know about them

its hard but youll get it,and come out with an easily obtainable A- like me

Ha! man I hope so.

I think my chemistry teacher's pulling out the only remaining hair he has with some of my class

just stay on top of the class by doing the extra bit of revision- which i didnt do, so it was surprising that i passed it at all!
