⩥ Alkene.
Answer: C=C
⩥ Alkyne.
Answer: Triple bonded carbons
⩥ Aromatics (arenes).
Answer: A ring structure with alternating double and single bonds.
Benzene, 6-sided one, is the most common.
⩥ Alcohol.
Answer: R-OH
If you think you see it, make sure it's not part of a carboxylic acid.
⩥ Ether.
Answer: R-O-R
If you think you see it, make sure it's not part of an ester.
, ⩥ Ketone.
Answer: A carbonyl group (C=O) with two Rs attached to the carbonyl
carbon. Neither R can be an H.
⩥ Aldehyde.
Answer: A carbonyl group (C=O) with one R and one H attached to the
carbonyl carbon.
⩥ Carboxylic acid.
Answer: A carbonyl group (C=O) with one R and one OH attached to
the carbonyl carbon.
⩥ Ester.
Answer: A carbonyl group (C=O) with one R and one OR group
attached to the carbonyl carbon.
⩥ Amine.
Answer: N attached to R or H groups. If you think you see it, make sure
it's not part of an amide.
⩥ Amide.
Answer: A carbonyl group (C=O) with one R group and one NR₂
attached to the carbonyl carbon.
