Question

Arrange ch3f, ch3cl, ch3br, ch3cl in increasing order of c-x bond enthalpies

Answer 1

CH3Cl>CH3F>CH3Br>CH3I

Answer 2

Explanation:

Energy necessary to break a bond between two atoms in order to break it into its constituent particles is known as bond enthalpy.

Therefore, smaller is the size of combining atoms more stronger will be the bond between them. As a result, more energy is required to break the bond hence, bond enthalpy will be high then.

Thus, we can conclude that increasing order of C-X bond enthalpies of the given compounds will be as follows.

            $CH_{3}F$ > $CH_{3}Cl$ > $CH_{3}Br$ > $CH_{3}I$
