Question

Consider the following reaction,
`{:(CHO" "COO^(-)),("| "+OH^(-) rarr "|"),(CHO" "CH_(2)OH):}`
Select the incorrect statement.
A. It is not a disproportionation reaction.
B. It is intramolecular redox reaction.
C. `OH^(-)` is a reducing as well as oxidising agent.
D. `{:(CHO),("|"),(CHO):}` is a reducing as well as oxidising agent.

Answer 1

Correct Answer - C
One CHO is oxidised to `CO O^(-)` and one CHO is reduced to `CH_(2)OH`.
Thus, it is not a disproportionation reaction. It is intramolecular redox reaction. Thus, options (a) and (b) are true and `{:(CHO),("|"),(CHO):}` is reducing as well as oxidising agent.
Thus, (d) is also true. Thus, (c) is incorrect.
