Answer 1

Chix I a ether, o°c No Reaction hace, the reaction pathway should be Sv 2 (Substitution Nucleophilic kimolecular). But the backside attack by the Ir at the ca carbon centre does not take place since , I is a weaker Nucleophile compared to ci So, the c-cl bond being stronger than c-I bond, the formation of the latter

does not take place. The reaction temperatwee was 0°C, which means the reaction was performed under cold conditions. 7.
