`underset("donor")underset("Hydride")(RCHO) + underset("Acceptor")underset("Hydride")(R'CHO )rarr R-overset(O)overset(||)C-O^(Θ)+R'CH_(2)OH`
select the correct statement.

A

Oxidation number of C in RCHO increases and that of `R'CHO` decreases.

B

Oxidation number of C in RCHO decreases and that of R'CHO increases.

C

Oxidation number of C remains unchanged in both but that of oxygen is affected.

D

In `CH_(3)CHO` and `C_(6)H_(5)CHO`, the former can act as RCHO (hydride donor).

Text Solution

Verified by Experts

The correct Answer is:
A
`RCHO (overset(Θ)(H) "donor")` is converted to `RCOO^(Θ)` and `R'CHO (overset(Θ)(H) "accepter")` is converted to `R'CH_(2)OH`. Therefore, RCHO is oxidised and `R'CHO` is reduced. In oxidation, the oxidation number increases and in reduction it decreases.
