Addition of $HCl$ to propene in the presence of peroxides gives:

Which of the following reagents can be used for the conversion of $1$-Methylcyclopentene to the given product?

Write the structures of all the alkenes which on hydrogenation give $2-$methylbutane.

What is the first step of the addition reaction when $HBr$ is added to propene in the absence of peroxide?

An unknown alkene $(A)$ reacts with $3 \ mole$ of $H_2$ gas in the presence of a platinum catalyst to form $1$-isopropyl-$4$-methylcyclohexane. When the unknown alkene $(A)$ is ozonized and reduced,the following products are obtained:
$HCHO$,$OHC-CH_2-CO-CO-CH_3$,and $CH_3-CO-CH_2-CHO$
What is the structure of alkene $(A)$?

$A$ hydrocarbon with molecular formula $C_6H_{10}$ absorbs only one molecule of $H_2$ upon hydrogenation. Ozonolysis of the hydrocarbon yields $OHC-CH_2-CH_2-CH_2-CH_2-CHO$. The hydrocarbon is:
