In many molecules, atoms attain complete octet by sharing more than one pair of electrons. which of the following correctly describes a triple covalent bond?

it results in a longer distance between the bonded atoms than does a single bond.

it results in a shorter distance between the bonded atoms than does a single bond.

it corresponds to the sharing of two pairs of electrons.

it is formed when two chlorine atoms form covalent bonds.

Option (b) is the correct answer.

Explanation:

A covalent bond is defined as the occurrence of a bond due to the sharing of electrons between the combining atoms.

So, when one pair of electrons is being shared by the combining atoms then a single covalent bond is formed.

When two pairs of electrons is being shared by the combining atoms then a double covalent bond is formed.

And, when three pairs of electrons is being shared by the combining atoms then a triple covalent bond is formed.

In a triple covalent bond, there is much more overlapping and as a result, distance between the atoms decreases. This means more is the overlapping taking place between the combining atoms more closer they will be towards each other.

Thus, we can conclude that the statement it results in a shorter distance between the bonded atoms than does a single bond, correctly describes a triple covalent bond.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
