which statement best describes the structural difference between aldehydes and
ketones? - CORRECT ANSWER-aldehydes contain a carbonyl group on an end carbon
of the carbon chain; ketones contain a carbonyl group on a carbon within the carbon
chain.
what type of product is formed in the reaction between an acid chloride and a

Which of the following is a generic acyl group? - CORRECT ANSWER-R-C!!O-
which type of compound is NOT classified as an alphatic hydrocarbon? - CORRECT
ANSWER-aromatic
Bromine(Br2) is often used as a quick test for the presence of unsaturation in a aliphatic
hydrocarbon. Bromine is CCL4 is red. When bromine reacts w alkene or alkyne, the
alkyl halide formed colorless; hence the disappearance of the red color is a positive test
for unsaturation..................... How may the results for vial B be interpreted? -
CORRECT ANSWER-Vial B must contain a cyclic compound.
