Question & Answer: Which of the following molecules contains at least one polar covalent bond? F_2 KCl…..

Hence

Option —(a)-wrong answer

Hence

Option —(b)-wrong answer

1. It is non-polar.
2. There is no difference in electronegativity between the 2 carbons.
3. the difference in electronegativity between C and H is minimal
4. It is a symmetrical molecule

Hence

Option —(c)-wrong answer

1. it contains a polar molecule between carbon and oxygen.

1. it is a covalent compound.

1. .all the electrons are shared and there is no transfer of electrons.
2. all the bonds are covalent with an electronegativity of less than 1.7 which means covalent.

Option —(d)-correct answer
