The product $(C)$ is:

What is the major product formed when $1, 3$-butadiene reacts with $1 \ mol$ of $HCl$ at high temperature ($100^{\circ}C$ or above)?

The volume of dihydrogen required for complete hydrogenation of $0.5 \ dm^{3}$ of ethene at $\text{S.T.P.}$ is (in $dm^{3}$)

$2-$methylbut$-2-$ene $\xrightarrow[\text{(ii) } Zn / H_2 O]{\text{(i) } O_3}$ products here are . . . . . . .

$(CH_3)_2C = CHCH_3 + NOBr \to$ product. The structure of the product is

$R_f$ value for $2$-methylpropene in a solvent system (Ethyl acetate + ether) is $0.42$. $2$-methylpropene is treated with dilute $H_2SO_4$ to give major organic product $(X)$. $R_f$ value for $(X)$ in the same solvent system under identical condition will be:
