Aryl halides are less reactive than alkyl halides towards nuceophilic reagents. Give reasons.

Assertion (A) : Tertiary alkyl halides are more reactive than 1^(@) alkyl halides towards elimination. Reason (R ) : Positive Inductive effect of alkyl groups weakens carbon-halogen bond in 3^(@) halides.

Statement-I:Primay benzylic halides are more reactive than primary alkyl halides towards S_(N^(1)) reaction. Because Statement-II: Reactivity depends upon the nature of the nucleophile and the solvent.

Amides undergo hydrolysis to yield carboxylic acid plus amine on heating in either aqueous acid or aqueous base. The conditions required for amide hydrolysis are more severe than those required for the hydrolysis of esters, anhydrides or acid chlorides, but the mechanism is similar (nucleophilic acyl substitution). Nucleophilic acyl substitutions involve a tetrahedral intermediate, hence these are quite different from alkyl substitution (RCH_(2)Broverset(NaCN)to RCH_(2)CN) which involves a pentavalent intermediate or transition state. One of the important reactions of esters is their reaction with two equivalent of Grignard reagent to give tertiary alcohols. Which of the following constitutes the best substrate during the acidic hydrolysis of amides?
