The symbol of Aryl group is "Ar".
An arylidene is an aryl derivative of a methylene group.
The aryl group is basically an abbreviation for an Aromatic group lake a hydrogen and also binding to a molecule (at where the H+atom is removed). It is like an Alkyl group but instead of an Alkan (aliphatic side chain of hydrocarbon) there is an aromatic group. So the structure of Aryl group is a side chain containing one or more aromatic group. I am just a pharmacy student I hope that I made it clear enough for you.
The reason is that the aryl group is able to stabalize the diazonium salt through resonance, while the alkyl group may not be resonance stabalized.
