The bond that is actually shorter has to be determined. Concept Introduction: Bond length is the distance between the centres of two covalently bonded atoms. Two important trends are: Down the group, the bond length between the atoms increases. Multiple bonds are shorter than single bonds. The steric number is the combination of both number of σ -bonds and number of lone pairs involved in a particular molecule. If the steric number is 4, the central atom is s p 3 hybridized and the electronic arrangement of atoms in space (i.e. geometry) will be tetrahedral. If the steric number is 3, the central atom is sp 2 hybridized and the electronic arrangement of atoms in space (i.e. geometry) will be trigonal planar. If the steric number is 2, the central atom is sp hybridized and the electronic arrangement of atoms in space (i.e. geometry) will be linear.

Chapter 1, Problem 72IP

Interpretation Introduction

Interpretation:

The bond that is actually shorter has to be determined.

Concept Introduction:

Bond length is the distance between the centres of two covalently bonded atoms.

Two important trends are:

Down the group, the bond length between the atoms increases.

Multiple bonds are shorter than single bonds.

The steric number is the combination of both number of σ -bonds and number of lone pairs involved in a particular molecule.

If the steric number is 4, the central atom is sp3 hybridized and the electronic arrangement of atoms in space (i.e. geometry) will be tetrahedral.

If the steric number is 3, the central atom is sp² hybridized and the electronic arrangement of atoms in space (i.e. geometry) will be trigonal planar.

If the steric number is 2, the central atom is sp hybridized and the electronic arrangement of atoms in space (i.e. geometry) will be linear.
