2.2 Methane and ethane representative alkanes 1) Methane and ethane are two members of a broad family of Organic compounds called hydrocarbon (% 2)Hydrocarbons are compounds whose molecules contain only carbon and hydrogen atoms-------- alkanes 3)Hydrocarbons whose molecules have a carbon-carbon double bond are called alkenes. and those with a carbon-carbon triple bond are called alkynes
2.2 Methane and Ethane: Representative alkanes 1）Methane and ethane are two members of a broad family of Organic compounds called hydrocarbon （烃） 2) Hydrocarbons are compounds whose molecules contain only Carbon and hydrogen atoms-------- alkanes 3) Hydrocarbons whose molecules have a carbon-carbon double bond are called alkenes, and those with a carbon-carbon triple bond are called alkynes
Saturated compounds and unsaturated compounds (饱和化合物和不饱和化合物) 1) Generally speaking, compounds such as the alkanes whose molecules contain only single bonds are referred to as saturated compounds 2) Compounds with multiple bonds, such as alkenes alkynes and aromatic hydrocarbons are called unsaturated compounds
