\[X\xrightarrow[\text{(Reductive)}]{Ozonolysis}Y+Z\] Y can be obtained by Etards reaction. Z undergoes disproportionation reaction with concentrated alkali. X could be

A)  

B)  

C)  

D)  

Correct Answer: B

Solution :

: Y is obtained by Etards reaction, Z  reacts with cone. \[NaOH\] \[\underset{\begin{smallmatrix}  Formaldehyde \\  Z \end{smallmatrix}}{\mathop{2HCHO}}\,+NaOH\xrightarrow[Cannizzaros\,reaction]{Dispropor\tan ation}\] \[\underset{Sodium\,formate}{\mathop{HCOONa}}\,+C{{H}_{3}}OH\]
