Question
With what neutral molecule is ClO− isoelectronic? Is that molecule a Lewis base?
Advertisements
Solution
ClO− is isoelectronic to ClF. Also, both species contain 26 electrons in all as shown.
Total electrons ClO− = 17 + 8 + 1 = 26
In ClF = 17 + 9 = 26
ClF acts like a Lewis base because the Cl atom has three lone pairs of electrons and can combine further with F to form ClF3.
