dude, when the electronegativity difference of two bonds is ( 1.7 - 1.8 ) , it denotes to 50 % ionic

character. if the electronegativity difference is more thn this, then ionic character predominates.

here , the electronegativity difference is 2. thus A-B bond has dominant ionic character.

% ionic character of A-B bond=16(x_a-x_b)+3.5(x_a-x_b)²
=16*2+3.5*4
=46

yup thats the formula for %age ionic character

its der in JD LEE as well

although ive wondered abt its correctness bcz it gives erroneous answers
