Butan-2-ol is heated with an H2SO4 catalyst.
A mixture of three alkenes form B, C and D.
The alkenes B and C are stereoisomers.
Draw the two structures of the two stereoisomers B and C.
My answer (incorrect):
I draw the double bond between the carbons and put the alkyl group CH3 on both sides to represent the E and Z isomers..
But I put OH and H, because butan-2-ol is an alcohol.
The mark scheme requires the other side group to only be H and not OH and H, alongside the alkyl group CH3 which was correct.
Can someone tell me why that is....
Appreciate the help from anyone.
