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.

Thanks for this described ans
thank u soooo much
Thanks.But you should also have to write more description.
Thanks
Write some more description
Thanks for your answer
As per ncert book's solution... It's correct.
Yes you are wrong It is Lewis base because of presence of lone pair on halogen
how it can be lewis base,you are wrong it lewis acid
How is it possible if it accepts an electron then it should be lewis acid..
