The major product of the reaction is:

Addition of $HBr$ to propene yields $2$-bromopropane,while in the presence of benzoyl peroxide,the same reaction yields $1$-bromopropane. Explain and give mechanism.

$CH_3-C(CH_3)=CH-CH_3 \xrightarrow{Hg(OAc)_2/EtOH} (A) (90\%)$. The product $(A)$ of the above reaction is:

The number of $sp^3$ hybridized carbon atoms in cyclohexene is

Ozonolysis of an alkene with molecular formula $C_{7}H_{14}$ in the presence of $Zn$ dust gives a mixture of acetone and $butan-2-one$. The $IUPAC$ name of the alkene is ..........
