Question

Which of the following species are isolobal? BF3, NH3, CH3+, CH3-

Answer 1

Given:- BF3, NH3, CH3+, CH3-

To find:- Which of the following species are isolobal

Solution:-

When two fragments have symmetrical properties, same shape and same number of electron of their frontier orbitals, called Isolobal.

And here CH3,BF3 and CH3- have same number of electrons so, they are known as Isolobal but NH3 is not Isolobal
