Solution
(a) The general name for the class of compounds having the formula CnH2n-2 is alkynes. Ethyne is the first member of the homologous series of alkynes.
(b) CnH2n is the general formula for the homologous series of alkenes. The second and the fourth member of this series will have the molecular formulae C3H6 and C4H8 respectively.
c) The third and fifth member of the series having the general formula CnH2n+2 (alkanes) will have the molecular formula C3H8 and C5H12 respectively​.
(b) CnH2n is the general formula for the homologous series of alkenes. The second and the fourth member of this series will have the molecular formulae C3H6 and C4H8 respectively.
c) The third and fifth member of the series having the general formula CnH2n+2 (alkanes) will have the molecular formula C3H8 and C5H12 respectively​.
