Mechanism :
[D form `LiAID_(4)` and `NaBD_(4)` is added to C of `(C=O)` group and solvent gives H or D to O atom to form OH or OD, eg.,]
i.
ii.
iii. LAH and `NaBH_(4)` do not reduce `(C=C)` bond, whereas catalytic hyhdrogenation reduces `(C=C)` bond to `(C--C)` bond.
iv. LAH and catalytic hydrogenation reduce epoxide but `NaBH_(4)` does not.
(A)
(A)
The D of ROD rapidly rapidly exchanges for the of `H_(2)O`.
Mechanism in (B):
Reactions:
The D of ROD rapidly exchanges for H of `H_(2)O`.
