Alkyl and Aryl Halides
Explanation:
Fiz uma busca no google por termos semelhantes aos em português.

Segundo o Michaelis:
Arila (sem h): Radical resultante da retirada de um hidrogênio de um hidrocarboneto alifático.
Alquila : Designação genérica dos radicais aromáticos monovalentes.

As mesmas definições aparecem em inglês no site: http://antoine.fsu.umd.edu/chem/senese/101/organic/glossary....

Quanto a Haletos, regra prática: -eto = -ide. Ex: brometo = bromide, cloreto = chloride.

Quanto ao uso, o site http://www.farmingdale.edu/CampusPages/ArtsSciences/Academic... (e vários outros)apresentam exatamente a expressão "alkyl and aryl halides".
