Asseration: Liquid `HF` is used as non-aqueous solvent and many acid-base reactions occur in this solvent system.
Reason: Liquid `HF` undergoes self ionisation.

An organic compound A (C_2H_3N) is used as a solvent of choice for many organic reactions because it is not reactive in mild acidic and basic conditions. Compound A on treatment with Ni/ H_2 fo rms B. When B is treated with nitrous acid at 273K, ethanol is obtained. When B is warmed with chloroform and NaOH, a foul smelling compound C is formed. Identify A to C along with their structures and given reactions.

Give reason in one or two sentences. "Ammonium chloride is acidic in liquid ammonia solvent".

Give reason in one or two sentences. "Ammonium chloride is acidic in liquid ammonia solvent".

Asseration: Mineral acids on dissolving in liquid HF acts like a base. Reason: Liquid HF acts as an acid and posses strong tendency to donate proton.

Assertion : The HF_(2)^(-) ion exists in the solid state & also in liquid state but not in aqueous state. Reason : The magniture of hydrogen bonds among HF molecules is weaker than that in between HF and H_(2)O .

Assertion : The HF_(2)^(-) ion exists in the solid state & also in liquid state but not in aqueous state. Reason : The magniture of hydrogen bonds among HF molecules is weaker than that in between HF and H_(2)O .
