1) In NH4Cl, the N-H bond is polar due to appreciable electronegativity difference between N (3.0) and H (2.1).

2) In HCN, the H-C and C-N bonds are polar due to electronegativity difference between C (2.5) and N (3.0) for H-C bond as well as between C (2.5) and H (2.1) for C-N bond.

3) In H2O2, the O-H bond is polar due to electronegativity difference between O (3.5) and H (2.1). Whereas, O-O bond is non-polar.

4) In CH4, the C-H bonds are also polar.
