Correct option: E
Hydroxide (HO-) is a very poor leaving group. Br- is not able to substitute HO-. Hence, no product will form.
20.
Correct option: B
HBr will protonate the alcoholic OH group. As a result, water will leave the molecule to give a secondary carbocation. Then, hydride shift from the neighboring carbon will yield more stable tertiary carbocation. Br- will then attack the tertiary carbocation to give the product.
21.
Correct option: D
PBr3 reacts with alcohol to yield alkyl bromide. This reaction goes via SN2 mechanism. Hence, inversion of configuration at the stereocenter takes place.
22.
Correct option: A
The above reaction is a substitution reaction as it substitute OH with Br.
