Question

Arrange the energy required to break all the bonds in each of the following bond types in descending order.

• A. Double bond, single bond, triple bond
• B. Triple bond, single bond, double bond
• C. Triple bond, double bond, single bond
• D. All the bonds require equal energy

Answer 1

The correct option is C Triple bond, double bond, single bond

As the number of shared electrons increases, the bond strength increases.
In a triple bond, totally 6 electrons are shared. In a double bond, totally 4 electrons are shared and in a single bond, only 2 electrons are shared. Thus, the bond strength is as follows:
Triple bond > double bond > single bond.
