A mixture of carbon monoxide, hydrogen and hydrocarbon is known as:
1 Water gas
2 Carburetted water gas
3 Semi water gas
4 Producer gas
Explanation:
: Mixture of $\mathrm{CO}+\mathrm{H}_2$ is water gas. Mixture of $\mathrm{CO}+\mathrm{H}_2$ +hydrocarbons is carburetted water gas. Mixture of $\mathrm{CO}+\mathrm{H}_2+\mathrm{CO}_2$ is called semi water gas. Mixture of $\mathrm{CO}+\mathrm{N}_2$ is called producer gas.

In Wurtz reaction, the reagent used is
1 $\mathrm{Na}$
2 $\mathrm{Na} /$ liq. $\mathrm{NH}_3$
3 $\mathrm{Na} /$ dry ether
4 $\mathrm{Na}$ /dry ethanol
Explanation:
: Wurtz reaction is the method of preparation of alkane from alkyl halide- explanation $\mathrm{RCl}+2 \mathrm{Na}+\mathrm{RCl} \underset{\text { Ethyr }}{\stackrel{\text { Dry }}{\longrightarrow}} 2 \mathrm{NaCl}+\underset{\mathrm{d}-\mathrm{law}}{\mathrm{R}-\mathrm{R}}$ The reagent used in the Wurtz reaction is sodium in the presence of dry ether.

A mixture contains four solid organic compounds A, B, C, D. On heating, only C changes from solid to vAPour state. $C$ can be separated from the rest in the mixture by
1 Distillation
2 Sublimation
3 Fractional distillation
4 Crystallisation
Explanation:
: On heating, only $\mathrm{C}$ changes from solid to vapour state. $\mathrm{C} \rightarrow \text { Solid } \stackrel{\text { Sublimation }}{\longrightarrow} \text { Vapour }$ Hence, $C$ can be separated by sublimation.
