Question

A section of the periodic table is given below with elements A,B and X,Y in two groups which of the bond given below is least ?

Answer 1

Please mark it as brainliest.

Answer: BY will be least polar because in a period of two consecutive groups atoms have very less difference of E.N. so they can cancel them out means unet will be approximately equals to zero.

AX is not the answer because when we go down the group E.N. decreases and B and Y are in lower position than that of A and X i.e.

their E.N. is more than BY.

Your answer is BY

Hope it helps..
