Solution: Alkanes are named using the ane ending, and with prefixes to indicate the number of carbon atoms in the longest carbon chain. For example, CH4 is called methane. Alkenes are named using the ene ending. The position of the double bond is indicated with a number designating the position of the bond in the carbon chain. The numbering starts at the end of the carbon chain closest to the double bond. For example, CH3CH=CHCH2CH3 or CH3CHCHCH2CH3 (or CH3CH2CH=CHCH3 and CH3CH2CHCHCH3) is called 2-pentene. Alkynes are named in a manner similar to the alkenes but using the yne ending. For example, CH3C≡CCH3 or CH3CCCH3 is called 2-butyne.The roots used to indicate the number of carbon atoms are given in the table below:
