- BII I III IV
- CV II III IV
- DII I V III
Correct answer
D. II I V III
Step-by-step solution
(a) B ₂ H ₆ is an electron deficient compound in Lewis terms, since two electrons are less available per bond and has 3-centre-2-electron bond in it. (b) CH ₄ is an electron precise hybrid since in this the number of electrons present is equal to the number of electrons required. (c) PH ₃ is an electron rich hybride in which the number of electrons present are more than the number of electrons required for making octet. (d) CaH ₂ is a saline hybride, since its structure is salt like.
