Question

What are $X$ and $Y$ in the following reaction?
Hex -2-ene $\stackrel{ O _{3}}{\longrightarrow } \text { Ozonide } \stackrel{ Zn + H _{2} O }{\longrightarrow } X+Y$

	X	Y
(a)	$CH_3CH_2CHO$	$\left( H _{3} C \right)_{2} CO$
(b)	$CH _{3} CH \left( CH _{3}\right) COOH$	$CH_3COOH$
(c)	$CH_3CH_2CH_2CHO$	$CH_3CHO$
(d)	$CH _{3} CH \left( CH _{3}\right) CHO$	$CH_3CHO$

• A. a
• B. b
• C. c
• D. c
• E. d

Answer 1

Answer: (C)

This reaction is known as ozonolysis where hex- 2 -ene reacts with $O _{3}$ to give ozonide which reduction gives butanal and ethanal as major products.
