C-N
electronegativity of C = 2.55
electronegativity of N = 3
The electronegativity difference = 3-2.55 =0.45
round off = 0.5
K-Br
electronegativity of K = 0.82
electronegativity of N = 2.96
The electronegativity difference = 2.96-0.82 = 2.14
round off 2.1
polar
F2S , BBr2, CH3Cl, HBr
non polar
CH4, N2
