 Please explain why the 2nd reaction is not possible? 5 Which of the following two reactions is not possible? HC104 a 4 2 + H20 HC104 @both@and@ @ none of these

Dear Student,

In second reaction carbocation is formed in cyclopropane (product side) which is least stable on comparing to cyclopropene, in simple the absence of "pi" bond in cyclopropane makes the carbocation an unstable pair with perchlorate anion. Hence second reaction is not feasible technically.
