Question

what is the influence of ring size on corbonyle IR absorbtion in cyclic keton​

Answer 1

Carbonyl stretching peaks generally fall between 1900 and 1600 cm-1 (assume all peak positions hereafter are in wavenumber units), a relatively unique part of the IR spectrum. This area is sometimes referred to as the carbonyl stretching region as a result.
