CH4( g)\mathrm { CH } _ { 4 ( \mathrm {~g} ) } are

40.39,1.67,1.83×10−540.39,1.67,1.83 \times 10 ^ { - 5 } and 0.4130.413 respectively arrange these gases in the order of their increasing solubility.

A

HCHO<CH4<CO2<Ar\mathrm { HCHO } < \mathrm { CH } _ { 4 } < \mathrm { CO } _ { 2 } < \mathrm { Ar }

B

HCHO<CO2<CH4<Ar\mathrm { HCHO } < \mathrm { CO } _ { 2 } < \mathrm { CH } _ { 4 } < \mathrm { Ar }

C

Ar<CO2<CH4<HCHO\mathrm { Ar } < \mathrm { CO } _ { 2 } < \mathrm { CH } _ { 4 } < \mathrm { HCHO }

D

Ar<CH4<CO2<HCHO\mathrm { Ar } < \mathrm { CH } _ { 4 } < \mathrm { CO } _ { 2 } < \mathrm { HCHO }

Answer

Ar<CO2<CH4<HCHO\mathrm { Ar } < \mathrm { CO } _ { 2 } < \mathrm { CH } _ { 4 } < \mathrm { HCHO }

Explanation

Solution

Higher the value of the lower is the solubility of gas in the liquid

Thus, the order of increasing solubility is

Ar<CO2<CH4<HCHO\mathrm { Ar } < \mathrm { CO } _ { 2 } < \mathrm { CH } _ { 4 } < \mathrm { HCHO }
