CHEM 2444 Lecture Notes - Lecture 3: Pi Bond, Alkane, Alkene

a. alkane (List only if no other functional class applies.)

g. ether

2) The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound containing C, H, and O exhibits strong, broad absorption band at 3430 cm^-1, a sharp band at 3300, and a band at 2200 cm^-1 (m).
Relative absorption intensity: (s)=strong, (m)=medium, (w)=weak.

What functional class(es) does the compound belong to?
List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly.
Do not over-interpret exact absorption band positions. None of your inferences should depend on small differences like 10 to 20 cm^-1.

The functional class(es) of this compound is(are).(Enter letters from the table below, in any order, with no spaces or commas.)

a. alkane (List only if no other functional class applies.)
