These are aliphatic hydrocarbons which form the homologous series of the saturated hydrocarbons. They have the general molecular formula of CnH2n+2. Each of the alkane member has its carbon in SP3 hybridized state in which all carbon atoms are tetrahedrally bonded with a bond angle ranging from 109.28 degree and 25% S-orbital character and 75% P-orbital character. They are made up of a single( sigma) bond. Examples are methane, ethane , propane e.t.c. They undergo combustion under much oxygen., substitution or replacement reactions(dehydrohalogenation) and elimination (dehydrogenation)reactions mainly.
