Identify the major product expected from the acid catalysed dehydration of 2-methyl-2-pentanol?

Answer 1

i didn't agree with the above answer. When it comes to acid catalyzed dehydration reaction, it will follow zaitsev's rule (some book refer as saytzeff's rule). Zaitsev's rule state that, when two or more possible alkene produced, the major product must be the alkene with highest substituent.

Based on this case, the major product is

CH3-C(CH3)=CH-CH2-CH3

named as 2-methyl-2-pentene. This alkene has 3 substituent
while below structure

CH2=C(CH3)-CH2-CH2-CH3 has only 2 substituent.
Based on Zaitsev's rule,the major product must be the most substituted alkene.
Hope i helped u.
Good luck!

Answer 2

The double bond woulod go to the end C atom:

CH2=C(CH3)CH2CH2CH3

I would call this 2-methyl pent-1-ene.
