Which contains both polar and non polar bonds? a) NH4Cl b) HCN C) H2O2 D) HClO2

please give proper method and solution not just option a or b plzzzz

Answered by admin @ 20/08/2021

I think it is H2O2 because

O-H bond is polar due to electronegativity difference between O and H.

O-H bond is non-polar.

Now,

Let us consider the remaining examples

NH4Cl: all the bonds are polar .

HCN: Both the C-H and the C-N bonds are polar
.

HClo2 is polar..

Hope this helps!
