Prolonged exposure of chloroform in humans many cause damage to liver. It is due to the formation of the following compound.
1 $\mathrm{CCl}_4$
2 $\mathrm{COCl}_2$
3 $\mathrm{CH}_2 \mathrm{Cl}_2$
4 $\mathrm{Cl}_2$
Explanation:
: Prolonged exposure of chloroform in humans many cause damage to liver. It is due to the formation of phosgene. When chloroform is oxidised, it forms phosgene with is poisonous.

Iodoform reaction is answered by all, except
: Iodoform test is used in laboratories for the detection of aldehydes and ketones containing an alpha methyl group. The compound $\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{OH}$ does not have either $\mathrm{CH}_3 \mathrm{CO}$ non $\mathrm{CH}_3 \mathrm{CH}(\mathrm{OH})$ group. Therefore the compound which not show positive result in iodoform test.

Methane can be converted into ethane by the reactions
1 Chlorination followed by the reaction with alcoholic $\mathrm{KOH}$
2 Chlorination followed by the reaction with aqueous $\mathrm{KOH}$
3 Chlorination followed by Wurtz reaction
4 Chlorination followed by decarboxylation
Explanation:
: Methane can be converted into ethane by the wurtz reaction. $\mathrm{CH}_4$ (Methane) is treated with chlorine gas in the presence of ultraviolet light to form chloromethane. Chloromethane is treated with sodium metal and dry ether to form the ethane. This process is called wurtz synthesis.

Cycloalkane formed when 1, 4-dibromopentane is heated with sodium is
1 Methyl cyclobutane
2 Cyclopentane
3 Cyclobutane
4 Methyl cyclopentane
Explanation:
: 1, 4-dibromopentane are treated with sodium or zinc then the product form cyclo alkane. This reaction is undergoes free radical mechanism.
