Question

What occurs in order to break the bond in a cl2 molecule? explanation please.

Answer 1

A cl2 molecule is a diatomic molecule composed of two atoms of identical halogen - chlorine. In this case, this molecule is composed of covalent bonds in which the identical atom- molecule tells that this is also non-polar. To break the bond, energy has to be absorbed to break the intermolecular force that bound the molecule together. 

Answer 2

Options for the question;

(1) Energy is absorbed.

(2) Energy is released.

(3) The molecule creates energy.

(4) The molecule destroys energy.

Answer:

(1) Energy is absorbed.

Explanation:

Using the Method of elimination;

Option 1 - Energy is absorbed to break bonds. Bond-breaking is an endothermic process. This means this option is correct.

Option 2 - This option is incorrect because bond breaking is endothermic in nature. Energy is being absorbed and not released.

Option 3 and 4 - These optons are wrong because energy can neither be created nor destroyed but can change from one form to another.
