The major product formed is (trans) 3-chlorobutan-2-ol + enantiomer.
Work Step by Step
The mechanism that gives this product is the addition of Halohydrins: 1) Electrophilic attack forms a chloronium ion. 2) Back-side attack by water on the most substituted carbon opens the chloronium ion. 3) Water removes a proton to give the chlorohydrin. The product + the enantiomer is formed.
