ISSUE:

Hello, can you help me with these reductions? I think that
A is false
B is true
C is true
D is false Concerning D I am in doubt between the use of LiAlH4 and NABH4 can someone clarify when NaBH4 is used to reduce?

(I understand that it is a weaker reducer than LiAlH4 and cannot reduce ester) thanks.

Hellooo!!

Boron reducer is too mild for esters. In this case, lithium aluminum hydride should be used. Greetings.
