Question

Answer the following question:
a. What is the basicity of $H_{3}P{O}_3$ and why?
b. Why does fluorine not play the role of a central atom in interhalogen compound?
c. Why do noble gases have very low boiling points?

Answer 1

(a) Two, as the structure of $H_{3}P{O}_3$ has two $P-OH$ bonds.

(b) This is due to smaller size and absence of $d$ orbitals in the valence shell of fluorine.

(c) Noble gases being monoatomic gases have no interatomic forces except weak dispersion forces, therefore they have low boiling points.
