Question

What type of molecule is polar in nature?

A. the atoms have an equal sharing of the electrons
B. the atoms have an unequal sharing of the electrons
C. there is an incomplete transfer of electrons
D. all are correct

Answer 1

Answer: B. the atoms have an unequal sharing of the electrons

Step-by-step explanation:

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

A polar moleucle is defined as a molecule which is formed when there is a difference of electronegativities between the atoms which leads to unequal sharing of electrons. example:
`HF`

Non-polar covalent molecule is defined as a molecule which is formed when there is no difference of electronegativities between the atoms which leads to equal sharing of electrons.Example:
`H_2`

Ionic bond is formed when there is complete transfer of electron from a highly electropositive metal to a highly electronegative non metal resulting into a neutral compound. Example;
`NaCl`
