CHEM 104 COMPREHENSIVE TEST PAPER
QUESTIONS AND ANSWERS VERIFIED
GRADED A+
●● 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.
