Compound (K) gives white precipitte with gas (I)

Compound (H) gives a white precipate with KF

Compound (K) can also be obtained by the action of dilute HCl on (F)

Compound (J) on strong heating `(gt 400^(@)C)` gives a solid residue and no gasesous products

The compound (B) is less soluble in water than (G)

Element (E ) is a good oxidising agent

Hydrolysis of (D) gives a gas which has carbon is sp hybridisation.

Hydrolysis of (D) gives a gas which has nitrogen in `sp^(2)` hybridation.
