WebCHAPTER 5. Alkyl Halides • Alkyl halides or haloalkanes or halogenoalkanes are the organic compounds which contain of the halogens group with a general formula of CnH2n+1X. • Aryl halides (Ar-X) is the halogen group that attach to the aromatic ring. X Example: Aliphatic Alkyl Halides. Br 1-bromopentane. Cl F 3-fluoro-6-methyloctane. 2 … WebPreparation of primary amines (RNH 2) via the SN2 reaction. Alkyl halides react via S N 2 with ammonia (NH 3) and amines as the attacking nucleophile. Because these are uncharged nucleophiles, it means that …
WebLesser will be the steric hindrance as felt by incoming nucleophile, and hence alkyl halide will be more reactive towards SN2 reaction. Based on the above, CH3Cl will react faster than (CH3)3CCl. 33.
