Chapter 6, Problem 29QRT

(a)

Interpretation Introduction

Interpretation:

From the given pairs of the bonds which one is shorter has to be identified.

  $\text{B-Cl}\text{or}\text{Ga-Cl}\text{.}$

Concept Introduction:

Bond length: It is defined as the average distance between nuclei of two bonded atoms in a molecule is called bond length.

The bond energy is directly proportional to the bond order and inversely proportional to the length.  The number of bonds increases the bond energy also increases.

If the bond order increases the bond strength also increases.

(b)

Interpretation Introduction

Interpretation:

From the given pairs of the bonds which one is shorter has to be identified.

  $\text{C-O}\text{or}\text{Sn-O}\text{.}$

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

From the given pairs of the bonds which one is shorter has to be identified.

  $\text{P-S}\text{or}\text{P-O}\text{.}$

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

From the given pairs of the bonds in Acrolein which one is shorter has to be identified.

  $\text{C=C}\text{or}\text{C=O}\text{.}$

Concept Introduction:

Refer to part (a).
