Textbook Problem

In each pair of bonds, predict which is shorter.

  1. (a) Si—N or Si—O
  2. (b) Si—O or C—O
  3. (c) C—F or C—Br
  4. (d) The C—N bond or the C≡N bond in H2NCH2C≡N

(a)

Interpretation Introduction

Interpretation:

The shortest bond in the given pair of bonds has to be determined.

Concept Introduction:

Bond length:

Bond distance or bond length is the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types.

Bond length depends upon the bond order. More the bond order the molecule has shorter bond length.

Explanation

Nitrogen and Oxygen falls in the same period; size of Nitrogen is larger than Oxygen. Hence the interatomic distance becomes larger in
