$2$-methyl-$2$-butene will be represented as:

$2-$hexene $\xrightarrow[(i) O_3]{(ii) H_2O}$ Products
The two products formed in the above reaction are -

An alkene $(A)$ $C_{16}H_{16}$ on ozonolysis gives only one product $(B)$ $C_8H_8O$. $(B)$ can also be obtained by the hydrolysis of the product obtained from the reaction between cyanobenzene and $CH_3MgBr$. $(A)$ shows geometrical isomerism and decolourises $Br_2$ water. $(B)$ on treatment with $SeO_2$ produces $(C)$. Which statement is not correct about $(A)$?

What is the product obtained by the reaction of $1$-butene with $HBr$ in the presence of peroxide?

Which alkene is most stable?

The reaction of $HBr$ with $CH_3-C(CH_3)=CH_2$ in the presence of peroxide will give:
