' A ' and ' B ' respectively are A. → _ (2) Zn - H _ 2 O ^ (1) O _...

' $A$ ' and ' $B$ ' respectively are

A. $\mathop{\to}_{\left(2\right)\text{ Zn } - {H}_{2}O}$ ^{ $\left(1\right){O}_{3}}$ Ethane- $1, 2$ -dicarbaldehyde $+$ Glyoxal/Oxaldehyde

B $\mathop{\to}_{\left(2\right)Zn - {H}_{2}O}^{\left(1\right){O}_{3}}5 -$ -oxohexanal

' A ' and ' B ' respectively are A. → _ (2) Zn - H _ 2 O ^ (1) O _ 3 Ethane- 1, 2 -dicarbaldehyde + Glyoxal/Oxaldehyde

' A ' and ' B ' respectively are A. → _ (2) Zn - H _ 2 O ^ (1) O _ 3 Ethane- 1, 2 -dicarbaldehyde + Glyoxal/Oxaldehyde

Options

A $1$ -methylcyclohex- $1, 3$ -diene & cyclopentene.
BCyclohex- $1, 3$ -diene & cyclopentene
CCyclohex- $1, 3$ -diene & $1$ -methylcyclopent- $1$ -ene
D $1$ -methylcyclohex- $1, 4$ -diene & $1$ -methylcyclopent- $1$ -ene

Correct answer

C. Cyclohex- $1, 3$ -diene & $1$ -methylcyclopent- $1$ -ene

Step-by-step solution

Compound $A$ is cyclohexa- $1, 3$ -diene

' A ' and ' B ' respectively are A. → _ (2) Zn - H _ 2 O ^ (1) O _ 3 Ethane- 1, 2 -dicarbaldehyde + Glyoxal/Oxaldehyde

Compound $B$ is $1$ -methylcyclopent- $1$ -ene

' A ' and ' B ' respectively are A. → _ (2) Zn - H _ 2 O ^ (1) O _ 3 Ethane- 1, 2 -dicarbaldehyde + Glyoxal/Oxaldehyde
