Question

which of the following is polar covalent bond:
a)0=0
b) C-L
c)H-H
d)H-F​

Answer 1

Answer:

Hydrogen fluoride (HF) can be described as a very polar molecule, while hydrogen (H2) is nonpolar. The origin of the polarization of the HF covalent bond has to do with electronegativity, an inherent property of all atoms.

Answer 2

Answer:

option d

Explanation:

covalent bond is between two non metal i.e. H and F. And after bonding due to small atomic size and high nuclear power F takes the electon of H and get negative charge while H gets a positive charge. Thus it is a polar covalent bond.
