Root Explanation

Phenyl is derived from 'phenol' (from Greek 'phaino' meaning to show or to appear) and the suffix '-yl' (used in chemistry to denote a radical or group derived from a compound). The term 'phenyl' refers to a specific group derived from phenol, which is a compound that shows certain properties in organic chemistry.

Memory Tip

Think of 'phenol' as a compound that 'shows' certain properties, and '-yl' indicates a group derived from it. This helps you remember that 'phenyl' refers to a group related to phenol.
