Section A

Section B

Ques. 9

Identify A and B.
(a) Reaction: ${\mathrm{CH}}_3-\mathrm{OH}+\mathrm{CO}\stackrel{\text{ catalyst }}{\to }$

This is a reaction of methanol $\left({\mathrm{CH}}_3\mathrm{OH}\right)$ with carbon monoxide $(\mathrm{CO})$, which is typically used to produce dimethyl ether in the presence of a suitable catalyst like ${\mathrm{H}}_2{\mathrm{SO}}_4$ (concentrated sulfuric acid). So, the reaction is:

${\mathrm{CH}}_3\mathrm{OH}+\mathrm{CO}\stackrel{{\mathrm{H}}_2{\mathrm{SO}}_4}{\to }{\mathrm{CH}}_3{\mathrm{OCH}}_3$

- A is Dimethyl ether $\left({\mathrm{CH}}_3{\mathrm{OCH}}_3\right)$.
(b) Reaction: ${\mathrm{CHCl}}_3+{\mathrm{Cl}}_2⟶(\mathrm{B})+\mathrm{HCl}$

This is a chlorination reaction of chloroform $\left({\mathrm{CHCl}}_3\right)$ with chlorine $\left({\mathrm{Cl}}_2\right)$, where chloroform reacts with chlorine to form carbon tetrachloride $\left({\mathrm{CCl}}_4\right)$ and hydrochloric acid $(\mathrm{HCl})$.
- B is Carbon tetrachloride $\left({\mathrm{CCl}}_4\right)$.

Ques. 10

10. The chemical formula of a compound is ${\mathrm{C}}_2{\mathrm{H}}_6\mathrm{O}$.
(a) Structural formula of any one functional isomer of ${\mathrm{C}}_2{\mathrm{H}}_6\mathrm{O}$ :
- Ethanol $\left({\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}\right)$ is one of the functional isomers of ${\mathrm{C}}_2{\mathrm{H}}_6\mathrm{O}$, where the functional group is a hydroxyl group $(-\mathrm{OH})$ attached to an ethane backbone.

The structural formula of ethanol is:

${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}$

(b) IUPAC name of this functional isomer:

The IUPAC name is ethanol.
