Question

Which of the following will be the best substrate for the synthesis of 2-methyl-2-pentene via dehydration?

A.) 2-methyl-3-pentanol

B.) 2-methyl-2-pentanol

C.) neopentyl alcohol

D.) 1-pentanol

E.) 2-methyl-1-pentanol

Answer 1

2- methyl- 2 - pentanol is the best substrate for the synthesis of  2- methyl -2 - pentene via dehydration because - After leaning water molecule it forms 3^o carbocation which is most state which forms substituted alkene.

Formation of 3^o carbocation and most substituted Alkene. there are the driving force.
