Key Differences
Acyl and Acetyl both pertain to organic chemistry, denoting functional groups found in various compounds. Acyl represents a broader category of organic compounds derived from carboxylic acids by removing a hydroxyl group. This group can be associated with different acids, thus giving rise to a variety of acyl groups.
Acetyl, on the other hand, is a more specific subset of acyl. It is derived specifically from acetic acid, making it a particular kind of acyl group. While acyl can form diverse compounds such as acyl chlorides or acyl anhydrides, depending on the acid it originates from, acetyl's reference is primarily towards compounds linked to acetic acid.
In summary, acyl denotes a wider range of compounds derived from various carboxylic acids, while acetyl is specifically related to acetic acid.

Acyl
(organic chemistry) Any of class of organic radicals, RCO-, formed by the removal of a hydroxyl group from a carboxylic acid.
Acetyl
(organic chemistry) The univalent radical CH3CO- derived from acetic acid.
Acyl
An acid radical, as acetyl, malonyl, or benzoyl. An acyl radical can be depicted as R-CO-, where -CO- is the carbonyl group, and R is the group that characterizes the acyl moiety.
Acetyl
A complex, hypothetical radical, composed of two parts of carbon to three of hydrogen and one of oxygen. Its hydroxide is acetic acid.
Acyl
Any group or radical of the form RCO- where R is an organic group;
An example of the acyl group is the acetyl group
