Question 58

Multiple Choice

Why is this sequence,CH₂=CHCH₂OH + HBr,then CrO₃/H₂SO₄/H₂O,finally xs NH₃,not a good method for the preparation of L-alanine?

A) NH₃ is not sufficiently nucleophilic to perform the final step.
B) HBr does not add to substituted alkenes.
C) 1° alcohols are not oxidized by CrO₃ in acidic solution.
D) Initial HBr addition produces a racemic intermediate which leads to racemic product.
E) Steric hindrance precludes nucleophilic substitution at a 2° carbon atom.
