Answer:
Iodoethane will undergo Sn2 faster than Bromoethane.
Explanation:
Because -I is a better leaving group. In Bromoethane, the C-Br bond is formed by 2p-4p overlapping while the C-I bond in Iodoethane is formed by 2p-5p overlapping. So, the C-Br bond is comparitively stronger than the C-I bond.
