STD 11 - 8.1. Organic chemistry Nomenclature of organic compounds — JEE STD 11 Science — Question

Assertion $A :$- Carbon forms two important oxides $- CO$ and $CO _2 . CO$ is neutral whereas $CO _2$ is acidic in nature.

Reason $R :$- $CO _2$ can combine with water in a limited way to form carbonic acid, while $CO$ is sparingly soluble in water.

In the light of the above statements, choose the most appropriate answer from the options given below :-

$\Delta S_A^o = 100\frac{J}{{mol \times k}}$   $\Delta S_C^o = 200\frac{J}{{mol \times k}}$

$\Delta S_B^o = 120\frac{J}{{mol \times k}}$   $\Delta S_D^o = 150\frac{J}{{mol \times k}}$
