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 $(A)$?

The disappearance of the characteristic purple colour of $KMnO_4$ in its reaction with an alkene is the test for unsaturation. It is known as

Write the $IUPAC$ names of the products obtained by the addition reaction of $HBr$ to $hex-1-ene$:

$(ii)$ in the presence of peroxide.

Predict the product of the following reaction: $CH_3-CH=CH_2 \xrightarrow[(2) NaBD_4]{(1) H_2O, Hg(OCOCH_3)_2} \text{Product}$
