3.1. Định nghĩa và phân loại (definition and classification)
Hydrocarbon có chứa một liên kết đôi carbon-carbon
được gọi là alkene;những hydrocarbon có chứa liên kết
ba carbon-carbon là alkyne. Các công thức chung của
chúng là:
Cả hai loại hydrocarbon này đều không bão hòa vì
chúng chứa ít hydrogen trên mỗi carbon hơn alkane
(CnH2n+2).
Alkane có thể thu được từ alkene hoặc alkyne bằng
cách thêm 1 hoặc 2 mol hydrogen:
