Reaction of trans-$2-$phenyl$-1-$bromocyclopentane with alcoholic $KOH$ produces:

An organic compound $A$ $(C_4H_9Cl)$ on reaction with $Na$/dry ether gives a hydrocarbon which on monochlorination gives only one chloro derivative. What is $A$?

The elimination reaction of $2-$bromopentane to form pent$-2-$ene involves:
$a$. $\beta-$Elimination reaction
$b$. Following Zaitsev rule
$c$. Dehydrohalogenation reaction
$d$. Dehydration reaction

Which of the following is most reactive towards ${S_N}^2$ reaction?

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 $Y$?

Match the following:
