Question

Coal gas is mixture of:

• A. ${\mathrm{CH}}_4+{\mathrm{H}}_2+{\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{S}$
• B. ${\mathrm{CH}}_4+{\mathrm{H}}_2+\mathrm{CO}+{\mathrm{H}}_2\mathrm{S}$
• C. ${\mathrm{CH}}_4+{\mathrm{H}}_2+\mathrm{CO}$
• D. Ethane,Propane,Butane

Answer 1

The correct option is C

${\mathrm{CH}}_4+{\mathrm{H}}_2+\mathrm{CO}$

The explanation for the correct option:

(c) ${\mathrm{CH}}_4+{\mathrm{H}}_2+\mathrm{CO}$

1. Coal gas is one of the most used fossil fuels.
2. It is a flammable gaseous mixture with a very unpleasant smell
3. It is obtained by the destructive distillation of coal i.e; heating in absence of air and formerly used for lighting and heating.
4. Coal gas is a mixture of mainly hydrogen$\left({\mathrm{H}}_2\right)$, methane$\left({\mathrm{CH}}_4\right)$, and carbon monoxide$\left(\mathrm{CO}\right)$ and some percentage of Ethylene(${\mathrm{CH}}_2={\mathrm{CH}}_2$).

Hence, the correct option is C
