Vedclass · Answer

(D) Step $1$: Debromination of $2,3$-dibromo-$5$-methylhexane with $Zn$ dust leads to the formation of $5$-methylhex-$2$-ene. Step $2$: Ozonolysis $(O_3)$ of $5$-methylhex-$2$-ene forms an ozonide intermediate. Step $3$: Reductive hydrolysis of the ozonide with $Zn/H_2O$ cleaves the double bond to yield two carbonyl compounds. The reaction is: $(CH_3)_2CH-CH_2-CH=CH-CH_3 + O_3 \rightarrow (CH_3)_2CH-CH_2-CHO + CH_3-CHO$. Thus,the products are $3$-methylbutanal $(P)$ and ethanal $(Q)$.

The major products $P$ and $Q$ in the following reaction sequence are:
