Question

Statement I : Halogen attached to bulky group undergo S_N2 reaction.

Statement II : Secondary alkyl halide react with excess C₂H₅OH undergo S_N1 reaction.

(1) Both statements are true 

(2) Statement I is true, II is false 

(3) Both statements are false 

(4) Statement I is false, Statement II is true

Answer 1

The correct option is (4) Statement I is false, Statement II is true.

When halogen attached to bulky group back side attack is not possible so S_N2 reaction does not takes place. Secondary alkyl halide reacts with excess of ethanol undergo S_N1 reaction.
