A) The LDA creates an enolate nucleophile to
react with the benzyl bromide in a
substitution reaction. However, the bromide
is not a good enough leaving group for this
reaction.
B) The LDA creates an enolate nucleophile to
react with the benzyl bromide in a
substitution reaction. However, the product
of this reaction would have one less CH2
group than the proposed product.
C) The LDA reacts rapidly with the alcohol
solvent creating an alkoxide base. This base
is a thermodynamic base and would remove
a proton from the more substituted position
resulting in alkylation at the other alpha
carbon.
D) The LDA creates an enolate nucleophile to

substitution reaction. However, the reaction
conditions are too cold and would result in
alkylation at the other alpha carbon
(thermodynamic) rather than the proposed
kinetic product.
