Question

the table shown below gives the bond dissociation energies for a single covalent bonds of carbon atoms with wlwment A B Z and D which element has smallest atoms...Explaination is necessary

Answer 1

i think its C-D please if it is correct tell me

Answer 2

Answer: Element D is the smallest atom amongst the given elements.

Explanation: We are given some elements forming single covalent bond with carbon- element.

So, the bond dissociation of the compound having larger amount will have the smallest atoms because the force of attraction of the nucleus and the electrons on the outermost shell will be more. Hence, more amount of energy will be required to dissociate the bond.

$\text{Bond dissociation}\propto \frac{1}{\text{Size of the atom}}$

So, from the given information, C-D compound has the highest bond dissociation energy and hence, element D will be the smallest.
