Which of the statements are correct about above reaction?

  • A
    (a) and (e) both are nucleophiles.
  • B
    In (c) carbon atom is sp3 hybridised.
  • C
    In (c) carbon atom is sp2 hybridised.
  • D
    (a) and (e) both are electrophiles.

Answer

  1. (a) and (e) both are nucleophiles.
  1. In (c) carbon atom is sp2 hybridised.

Explanation:

HO– and CF– are nucleophiles. In (c), C atom is sp2 hybridised due to formation of C–OH bond and breaking of C – Cl bond simultaneously. So, in transition state, C atom is bonded to only 3 H atoms completely.
