The product $(A)$ formed in the following reaction sequence is :
$CH_3-C \equiv CH$ $\rightarrow[(ii) HCN]{(i) Hg^{2+}, H_2SO_4}$ $\xrightarrow[(iii) H_2 / Ni]{} (A)$

Which of the following alkenes,on reaction with dil. $H_2SO_4$,does not produce the following alcohol?

Explain the addition of sulphuric acid to alkenes with the help of a reaction.

One mole of $2-$methylbuta$-1, 3-$diene on ozonolysis gives:

$A$ hydrocarbon '$X$' with formula $C_6H_8$ uses two moles of $H_2$ on catalytic hydrogenation of its one mole. On ozonolysis,'$X$' yields two moles of methane dicarbaldehyde (malonaldehyde). The hydrocarbon '$X$' is :
