The [alkyl] groups derived by removal of a hydrogen atom from a terminal carbon atom of unbranched alkanes form a subclass of normal alkyl (_n-alkyl) groups H[CH₂]n. The groups RCH2, RxCH (R [not equal to] H, and R₃C (R [not equal to] H are primary, secondary and tertiary alkyl groups, respectively.  4, record 2, English, - alkyl%20group

Se usa la designación de amina primaria secundaria o terciaria para referirnos al número de grupos alquilos que están unidos al nitrógeno. Así, si la amina tiene un grupo alquilo y dos hidrógenos se le conoce como primaria, si tiene dos alquilos y un hidrógeno, secundaria y con tres grupos alquilo sin hidrógeno, terciaria.  2, record 2, Spanish, - grupo%20alquilo
