Atypical double bond a. is stronger and shorter than a single bond b. consists of one σ bond and one π bond c. imparts rigidity to a molecule d. consists of two shared electrons pairs e. all of the above answers are correct.

All of the above answers are correct.

Explanation:

Double bonds are stronger that single bonds because they have both sigma and pi bonds whereas single bonds contain only sigma bond. They also involve the sharing of electron pairs and heavily imparts rigidity to a molecule.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.
