Question

Statement-I : The order of base catalysed hydrolysis of ester is
1) C H subscript 3 end subscript minus C O O C H subscript 3 end subscript greater than C H subscript 3 end subscript minus C O O C subscript 2 end subscript H subscript 5 end subscript greater than C H subscript 3 end subscript minus C O O C H open parentheses C H subscript 3 end subscript close parentheses subscript 2 end subscript
2) 
Statement-II : S subscript N to the power of 2 end exponent end subscript The reaction is sterically as well as electronically controlled reaction.

  1. Statement-I is True, Statement-II is True ; Statement-II is a correct explanation for Statement-I    
  2. Statement-I is True, Statement-II is True ; Statement-II is NOT a correct explanation for Statement-I    
  3. Statement-I is True, Statement-II is False.    
  4. Statement-I is False, Statement-II is True    

The correct answer is: Statement-I is True, Statement-II is True ; Statement-II is a correct explanation for Statement-I


    S subscript N to the power of 2 end exponent end subscript Th is a sterically as well as electronically controlled reaction i.e., steric crowding around acyl carbon decreases rate of reaction and inerease in +ve charge centre around acyl carbon increases rate of reaction:
