Select all correct statements about the anion shown.

  1. AThe negative charge is delocalised onto the ortho and para carbons
  2. BIt is more stable than the ethyl carbanion
  3. CThe negative charge is delocalised onto the meta carbons
  4. DThe benzylic carbon becomes sp2-like to overlap with the ring

Answer: A, B, D

The anion shown is the benzyl anion. The charge is delocalised onto ortho and para ring carbons (A true), making it more stable than an ethyl anion (B true). The meta carbons never carry the charge (C false). To overlap with the ring, the benzylic carbon is planar sp2 (D true).
