What can be said about the shape of the infrared stretch of the o-h functional group in a carboxylic acid.?

Explanation:

Since carboxylic acids have an -OH group, they can form dimers by hydrogen bonding (see on attachment).

Because of this property of forming dimers, the hydrogen bond is stronger than in alcohols and phenols.  This translates into a wider absorption band and more displaced towards lower frequencies.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
