Alkenes and Alkynes are named by recognizing the longest chain, which comprises double or triple bonds. The ene suffix signifies if it is an alkene or cycloalkene. Alkenes are acyclic hydrocarbons with one carbon to carbon double bond and the general molecular formula. They are named using a s...
如: 3-Ethyl-2-methylhexane 4-ethyl-3,3-dimethylheptane 复杂的烷烃命名时须注意分子中有两个等长碳链时,按以下原则进行比较: 1)带支链数目较多者为主链,例如: 2,3,5-Trimethyl-4-propylheptane 2)支链定位号较小者为主链 2 烯烃和炔烃(alkenes and alkynes) 2.1 命名 4-Isobutyl-2,5-dimethy...

Alkenes: contain at least one C=C double bond.Alkynes: contain at least one C ≡C triple bond. Both alkenes and alkynes are known as unsaturated hydrocarbons Aromatic hydrocarbons: contain a benzene structure Lewis structures of alkanes look like this: These are also called structural formulas....
IUPAC ORGANIC NOMENCLATURE
Alkanes, alkenes, and alkynes (and sometimes the derivatives of benzene) are represented by the symbol R. these groups are also referred to as hydrocarbyl groups since they contain only carbon and hydrogen atoms. However, they may vary in the types of bonds between two carbon atoms, such as...
