Root Explanation

Alkyl is derived from the Arabic word "al-kuḥl" (meaning the kohl or black powder) and the suffix "-yl" (used in organic chemistry to denote a radical or group derived from a parent compound). The term "alkyl" refers to a group of carbon and hydrogen atoms derived from alkanes, which are saturated hydrocarbons.

Memory Tip

Think of 'al-kuḥl' as a base that refers to a specific group of atoms, and remember that 'alkyl' represents a group derived from alkanes, which are simple hydrocarbons.
