CHM247H1 Chapter Notes - Chapter 24: Alkane, Coupling Reaction, Bromine
Document Summary
Lone pair of electrons on n: defines much of amine chemistry. Note: when speaking of tertiary alcohol or alkyl halide referring to the degree of substitution at the alkyl carbon atom; but when speaking of tertiary amine referring to the degree of substitution at nitrogen. For 1 amines, use the suffix amine . Longest alkyl group is parent; list others alphabetically. When n is not the highest priority group (i. e. amine as a substituent: use prefix amino . Defined by degree of substitution on n: primary, 1 (r-nh2, secondary, 2 (r2nh, tertiary, 3 (r3n, quaternary ammonium salt, 4 (r4n+x-, note: lone pair is used up to accommodate 4th substituent on n. Nitrogen atom is sp3 hybridized: tetrahedral, 3 substituents in 3 corners of tetrahedron, one lone pair of electrons in the fourth corner. Jasmyn lee: unlike chiral carbon compounds can"t be resolved because two enantiomer forms rapidly interconvert by a pyramidal inversion.
