Question

Group the following as linear and non-linear molecules:

\[\ce{H2O, HOCl, BeCl2, Cl2O}\]

Answer 1

The molecules containing oxygen atom have the presence of two lone pair of electrons and due to lone pair-lone pair repulsions the molecules \[\ce{H2O, HOCl, Cl2O}\] will have a non-linear shape.

The structure of \[\ce{BeCl2}\] as the central beryllium atom will not have any lone pair of electrons.
