At $25,^oC$,Ethylene glycol is a:

What is the product $CH_3-CH_2-CHCl-CH_3$ obtained by the chlorination of $n$-butane?

Different hydrogen atoms in the compound $CH_3-CH=CH-CH_2-CH_2-CH(CH_3)_2$ are represented by alphabets $A, B, C, D, E, F$. Arrange them in decreasing order of reactivity towards free radical substitution.

$CH_3COOH$ $\xrightarrow{\text{Sodalime}} (A)$ $\xrightarrow{Br_2 / hv} (B)$ $\xrightarrow[KOH]{\text{Aq.}} (C)$ is $:-$

Which one of the following reactions gives the product with a lesser number of carbon atoms than the starting material?

An alkane $(Y)$ requires $8$ moles of oxygen for complete combustion and on chlorination with $Cl_2/h\nu$, $(Y)$ gives only one monochlorinated product $(Z)$. The total number of primary carbon atoms in $(Y)$ is . . . . . . .
