The product of the reaction is:

The dehydrobromination of $2-bromobutane$ gives $CH_3-CH=CH-CH_3$. The product is

An isomer of $C_5H_{12}$ on reaction with $Br_2 / \text{light}$ gave only one isomer $C_5H_{11}Br(X)$. Reaction of $X$ with $AgNO_2$ gave $Y$ as the major product. What is $Y$?

The correct description of the product in the following reaction is:
$CH_3-CH(Br)-CH_2OCH_3 \text{ } ((R)) \xrightarrow{NaCN, \text{acetone}} CH_3-CH(CN)-CH_2OCH_3$

Identify the major product formed from the following reaction: $1$-methylcyclohex-$1$-ene $\xrightarrow[(ii) AgNO_2]{(i) HCl} ?$
