Answer 1

Answer #1

2p-1s overlapping occurs in B&H which is relatively stable so this bond does not breakdown on room temperature. So it's difficult to obtain H- .

Oxygen of ester shows +R effect which reduces partial positive charge on carbonyl Carbon so H- attack becomes difficult.

NaBH4 is weak reducing agent which reduces only aldehyde, ketone, acid halide.

It can't reduce ester, so no Reaction will occ

Answer- 6.F No Reaction

Na B H4 EXOH, 25°C Reagent: Na Bha : Sodium besohydride + Reducing agent V H Nat BHA 1 B н Birth GH H न » strong bond → Na Bl
