Atoms in the water molecule are linked by

What will happen if $CCl_4$ is treated with $AgNO_3$?

The table shown below gives the bond dissociation energies $E_{diss}$ for single covalent bonds of carbon $C$ atoms with elements $A, B, C$ and $D.$ Which element has the smallest atoms?

$Bond$	$E_{diss} (kJ \ mol^{-1})$
$C-A$	$240$
$C-B$	$328$
$C-C$	$276$
$C-D$	$485$

Which of the following bonds requires the highest bond energy to dissociate the bonded atoms?

Multiple covalent bonds exist in a molecule of
