Chapter : 6. Carbon and Its Compound
Alkanes
48. Alkanes : All compounds in which carbon and hydrogen are attached with single bonds are called alkanes. The general formula of alkane from which all the members of family can be derived is CnH2n+2, e.g., CH4, C2H6, C3H8 C4H10, C5H12, C6H14
49. Alkenes : Those unsaturated hydrocarbons which have one or more double bonds are called alkenes. Their general formula is CnH2n, e.g., C2H4 (ethene), C3H6 (propene), C4H8 (butene), C5H10 (pentene), etc.
50. Alkynes : Those unsaturated hydrocarbons which contain one or more triple bonds are called alkynes. The general formula of alkynes is CnH2n–2, e.g., C2H2 (ethyne), C3C4 (propyne), C4H6 (butyne), C5H8 (pentyne), C6H10 (hexyne)
57. Unsaturated Hydrocarbons : Those hydrocarbons which contain at least on double or triple bond between two carbon atoms.
Double bond is formed by sharing of two pairs of electrons, e.g., Ethene is
Triple bond is formed by sharing of three pairs of electrons between two carbon atoms, e.g., Ethyne is
