(a)

Interpretation Introduction

Interpretation:

Out of C-C triple bond and C-N triple bond, that appears at higher wave number in IR spectrum needs to be determined given that both have same strength.

Concept Introduction :

There is large variance in force constant with small changes to bond length. The wavenumber is inversely proportional to square root of reduced mass. Hence, there is increase in reduced mass with decrease in wavenumber.

(b)

Interpretation Introduction

Interpretation:

Whether the reduced mass or stretching frequencies of C-N is in accordance with experimental data or not needs to be determined.

Concept Introduction :

Small changes in bond length leads to large variances in force constant. Also, it is known that wavenumber is inversely proportional to square root of reduced mass. Therefore, decrease in wavenumber is associated with reduced mass.
