Carboxylic acid groups consist of two very polar functional groups. Carbonyl group. Hydroxyl group. Carboxylic acid groups are very polar. Preparation of Esters Lab. Esters are responsible for the “fruity” . odours. and . flavours. of many naturally occurring products. Chemists can reproduce these . odours. or . flavours. in the lab by mixing the right alcohol and carboxylic acid together; thus producing “artificial” or “synthetic” versions of these naturally occurring compounds..
