Question

A molecule XY2 contains two sigma bonds, two π-bonds and one lone pair of electrons in the valence shell of X. The arrangement of lone pair as well as bond pairs is: (A) square pyramidal (B) linear (C) trigonal planar (D) unpredictable

Tardigrade Admin · Accepted Answer

The valence shell of X has two σ-bonds and one lone pair of electrons. Therefore, it has planar triangular geometry. It may be mentioned here that bond pairs involved in the formation of π - bonds are not considered while deciding the geometry of the molecule.

Q. A molecule $X Y_{2}$ contains two sigma bonds, two $π$ -bonds and one lone pair of electrons in the valence shell of $X$ . The arrangement of lone pair as well as bond pairs is:

square pyramidal

linear

trigonal planar

unpredictable

The valence shell of $X$ has two $σ$ -bonds and one lone pair of electrons. Therefore, it has planar triangular geometry. It may be mentioned here that bond pairs involved in the formation of $π -$ bonds are not considered while deciding the geometry of the molecule.
