ACTUAL QUESTIONS WITH
VERIFIED ANSWERS.
1. Aldehydes - correct answer-Hydrocarbon derivatves in which
two of the hydrogen atoms, attached to a terminal carbon,
have been replaced by a double-bonded oxygen atom
(carbonyl group). Noted by the suffix "-al"
2. Ketones - correct answer-Organic compounds containing the
carbonyl group attached to two organic radicals. Noted by
the suffix "-one"
3. Ethers - correct answer-An organic compound whose
molecules have two alkyl groups joined to the same oxygen
atom (R-O-R). Noted by the suffix "-oxy" and "-ane"
4. Amines - correct answer-Organic compounds derived from
ammonia by replacement of one or more of its hydrogen
atoms by one or more hydrocarbon radicals (R-NH-R). Noted
by the prefix "amino-"

5. Amides - correct answer-Organic compounds whose
molecules have a carbonyl nitrogen bond. They are the
product formed in a reaction between a carboxylic acid and
an amine.
