Condensation is the process of conversion of a substance present in vapor state to to liquid state. Clouds are formed when water vapor present in air condenses and changes from vapor to liquid state. The fast moving, energetic water molecules present in the vapor state, when encounter a cooler surface slow down during condensation and come closer to form a liquid.

So the correct answer will be,

A. molecules come closer and stick to each other.

Condensation is conversion of vapours to liquid

in vapour the molecules of water are far from each other and can move here and there. When a liquid like water condense the molecules come closer to each other.

Thus come closer together and stick to each other.

Provide the missing arrows in the boxes to show how br2 is produced from nbs
Illusion [34]

Answer: -

The mechanism for Br production from NBS is shown in the attached file.

N-bromo succinimide is a reagent used to brominate. It is most commonly used in allylic bromination, where a hydrogen on a carbon adjacent to a double bond is replaced.

It is selective in nature, unaffecting the normal double bond as compared to only bromine.

It also has a low concentration of bromine as an added advantage.
