Q 10 please

A set of three nucleophilic displacement reactions is shown below: - Br -Br -Br "CHз Hзс CHз C В A NaCN CH-он SN2 reaction Which reaction (A, B, or C) proceeds the fastest? Which reaction (A, B, or C) proceeds the slowest?

Provide the correct sequence of the steps involved in the following reaction: H3C CH2 H3C Br2 HBr но Br Step 1 [Choose] Nucleophilic attack on Bromine Carbocation rearrangement Proton transfer to bromide ion Step 2 Nucleophilic attack by water Leaving group leaves Nucleophilic attack by hydroxide Step 3 Generation of bromonium ion Step 4 [ Choose ]

How do I rank these from best to poorest leaving group? Do I base it in the size of the electronegative atom size?
