To solve this problem, we need to determine which compound will be most readily dehydrated under acidic conditions.$\newline$Dehydration of alcohols typically involves the formation of a carbocation intermediate. The stability of this intermediate is crucial.$\newline$The more stable the carbocation, the more readily the alcohol will dehydrate.$\newline$Let's analyze each option:$\newline$• Option 1: The alcohol is secondary, and the presence of the $NO_2$
