Question

hydrogen chloride and methane both contains the common element hydrogen.Even then an aqueous solution of hydrogen chloride is termed an acid while that methane is not ? give reason

Answer 1

Explanation:

Methane is not soluble in water and if it was it would not ionize in water. The acidic hydrogen needs to be attached to a highly electronegative atom or group that can form a stable anion - like HCl, for example: 

H-Cl ===> H^+ + Cl^- 

Methane cannot have this kind of behavior because the electronegativities of C and H are very similar.
