Correct answer: (a) NO+ is not isoelectronic with O2
Explanation:
NO+ = 7 + 8 – 1 = 14 e-.
O2 = 16 e-
i.e not isoelectronic
(b) Boron forms only covalent compounds. This is due to its extremely high ionisation energy.
(c) Compounds of Tl+ are much more stable than those of Tl3+.
(d) LiAlH4 is a versatile reducing agent in organic synthesis
