Explain why inspite of nearly same electronegativity, oxygen forms hydrogen bonding while chlorine does not.

Explain why inspite of nearly the same electronegativity, nitrogen forms hydrogen bonding while chlorine does not.

Why does NH_3 form hydrogen bonds but PH_3 does not ?

Why does NH_3 form hydrogen bond but PH_3 does not?

Explain why ozone is thermodynamically less stable than oxygen.

Why Xe forms compounds with fluorine and oxygen only?

Phosphorus forms a variety of oxyacids. In all these, phosphorus is sp^3 hybridised and is tetrahedrally bonded to four neighbouring atoms. These contain P-OH bonds, the hydrogen of which are ionisable giving acidic character to these compounds. These also contain P-H bonds in which hydrogens are notionisable because P and H have nearly same electronegativity. The presence of P-H group in these oxyacids is responsible for their reducing properties. The structures of some oxyacids are given below : Answer the following (1 to 7) questions : The oxyacid of P having tetrabasicity is

Explain, why ionization enthalpy of oxygen is smaller than nitrogen ?

Explain why bending a wire does not affect electrical resistance.
