2. What is the molecular geometry around an atomin a molecule or ion which is surrounded by fivesingle bonds and no lone pairs of electrons.a. trigonal bipyramidalb. octahedralc. lineard. trigonal planare. tetrahedral

VSEPR theory helps us to predict the shape and geometry of the molecules or ion. According to the VSEPER theory, if an atom is surrounded by five single bonds and no lone pair then the molecular geometry is trigonal bipyramidal with an angle of 90&ordm; at axial and 120&ordm; at equatorial.In PCl5, the P atom is bonded to 5 Cl with single bond and has no lone pair of electron. So the molecular geometry is trigonal bipyramidal. The structure is shown as follows:

The molecular geometry is octahedral around an atom in a molecular or ion if the atom is surrounded by 6 bond pair and no lone pair of electron.

The molecular geometry is linear around an atom in a molecular or ion if t...
