What could be the nature of A – B bond, if the electronegativities of A, B are 3.5 and 2.5 respectively?

Answer»

The “electro negativities” of “A” and “B” are GIVEN as 3.5 and 2.5 The “nature of the BOND” formed between A-B is to be found The difference in electro NEGATIVE VALUES of A and B = 3.5 - 2.5 = 1 The BONDS with the electro negative values less than 1.6 are considered to be polar. Since, the difference value is 1, the nature of A-B Bond is polar.
