Q.
The table shown below gives the bond dissociation energies $\left(E_{\text {diss }}\right)$ for single covalent bonds of carbon $(C)$ atoms with element $A, B, C$ and $D .$ Which element has the smallest atoms?
Bond
$E _{\text {diss }}\left( k J m o l ^{-1}\right)$
$C -A$
240
$C -B$
328
$C -C$
276
$C -D$
485
| Bond | $E _{\text {diss }}\left( k J m o l ^{-1}\right)$ |
