In IUPAC nomenclature, an acetyl group is called an ethanoyl group. An acetyl group contains a methyl group ( −CH 3 ) that is single-bonded to a carbonyl ( C=O ), making it an acyl group . The carbonyl center of an acyl radical has one non-bonded electron with which it forms a chemical bond to the remainder (denoted with the letter R ) of the ...
The cheerleader effect, also known as the group attractiveness effect or the friend effect, [1] is a proposed cognitive bias which causes people to perceive individuals as 1.5–2.0% more attractive in a group than when seen alone. [2]
When a mental state is shared by a large proportion of the members of a group or society, it can be called a collective mental state. Gustave Le Bon proposed that mental states are passed by contagion, while Sigmund Freud wrote of war fever in his work Group Psychology and the Analysis of the Ego (1922), a perfect example of the collective ...
It introduces an acetyl group into a chemical compound. Such compounds are termed acetate esters or simply acetates. Deacetylation is the opposite reaction, the removal of an acetyl group from a chemical compound.
For example, if part of a shape's border is missing people still tend to see the shape as completely enclosed by the border and ignore the gaps. This reaction stems from the mind's natural tendency to recognize patterns that are familiar and thus fill in any information that may be missing.
Used in a more general sense, the term X,Y-acetal also refers to any functional group that consists of a carbon bearing two heteroatoms X and Y. For example, N,O-acetal refers to compounds of type R 1 R 2 C(OR)(NR' 2) (R,R' ≠ H) also known as a hemiaminal ether or Aminal, a.k.a. aminoacetal.

The characteristic might be so salient that it could dominate the way that members of that clique are perceived and treated by other peers regardless of the individual differences that each member has. For example, a clique group could be perceived as athletic, but say an individual in that group is very smart and gets good grades in school.
