Answer to Question #60396 in Chemistry for 25

Question

The i.r. spectrum of a compound C2H4O2 has an absorption at 1700nm-1 but no absorption in the range 2500-3500cm-1. Suggest the structure of the compound.

In detail please

Answer 1

Answer:
The IR spectrum peak at ~1700 cm-1 is an indicative of a carbonyl group.
Usually broad absorption in the 2500-3500 cm-1 range is an indicative of an OH group. Since there is no any absorption in this range in the current case, there is no an OH group in the structure of a considered substance.
