Secondary alkyl halides classification

Alcohols and alkyl halides are classified as primary, secondary, or tertiary according to the classification of the carbon that bears the functional group (Section 2.10). Thus, primary alcohols and primary alkyl halides are compounds of the type RCH2G (where G is the fnnctional group), secondary alcohols and secondary alkyl halides are compounds of the type R2CHG, and tertiary alcohols and tertiary alkyl halides are compounds of the type R3CG. 

Alkyl halides are classified as being primary (1°), secondary (2°), or tertiary (3°). This classification is based on the carbon atom to which the halogen is directly attached. If the carbon atom that bears the halogen is directly attached to only one other carbon, the carbon atom is said to be a primary carbon atom and the alkyl halide is classified as a primary alkyl halide. If the carbon that bears the halogen is itself directly attached to two other carbon atoms, then the carbon is a secondary carbon and the alkyl halide is a secondary alkyl halide. If the carbon that bears the halogen is directly attached to three other carbon atoms, then the carbon is a tertiary... 

Notice that the number of alkyl groups attached to the nitrogen determines whether an amine is primary, secondary, or tertiary. For an alkyl halide or an alcohol, on the other hand, the number of alkyl groups attached to the carbon to which the halogen or the OH is bonded determines the classification (Sections 2.4 and 2.6).
