Question
Compare the IR carbonyl stretching frequencies of the following compounds to
that of acetone. Compare the table as follows:
(a) State whether the carbonyl stretching frequency is higher, lower, or about the
same
as acetone
(b) State the dominant effect responsible for the change in frequency relative to
acetone (i.e., resonance, inductive, mass change, none)
(c) Rank the compounds with numbers 1 through 4 in order of carbonyl stretching
frequency from highest to lowest (1 = highest; 4 = lowest)
