With what neutral molecule is ClO− isoelectronic? Is that molecule a Lewis base?
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 as it accepts electrons from F to form ClF3.
CIO– has 17 + 8 +1 = 26 electrons.Also, OF2 has (8 + 2 x 9) = 26 electrons, and ClF has (17 + 9) = 26 electrons.Out of these, ClF can act as Lewis base. The chlorine atom has three lone pair of electrons which it donates to form compounds like ClF3, ClF5 and ClF7
