Also known as
1-HEXENE, Hexene-1, Butylethylene, Hexylene, 1-n-Hexene, Butyl ethylene

概览

Its terminal CH2 group prevents E/Z isomerism. Addition across the double bond changes only that local unsaturation; the rest of the chain remains saturated. Bromine addition under suitable nonaqueous conditions gives a vicinal dibromide.
