Explanation:

Since the first member of alkyne series has 2 carbon atoms in it, therefore, the fifth member of alkyne series will have 6 carbon atoms in it. So, if we substitute n = 6 in the general formula CnH2n – 2 then the molecular formula of the fifth member of the alkyne series will be C6H2 × 6 – 2 or C6H10.

The fifth member of the alkyne series is Hexyne (C_6H_1_0).

Explanation:

  • The general formula of alkynes is C_nH_2_n _- _2 , where n = 2, 3, 4, 5, 6 ...
  • For the fifth member of the alkyne series n = 6
  • Put n = 6 in the general formula of alkynes is C_nH_2_n _- _2
  • The fifth member of the alkyne series = C_6H_2 _\times _6 _- _2
  • The fifth member of the alkyne series = C_6H_1_2 _-_ 2

The fifth member of the alkyne series = C_6H_1_0

  • Hexyne is an unsaturated hydrocarbon consisting of a six-carbon straight chain with a terminal alkyne.
  • The molecular formula of Hexyne is C_6H_1_0.
  • At room temperature, Hexyne is liquid and is pale yellow or colourless.
  • Hexyne is used in pharmaceuticals, agrochemicals, and in perfumery industries to produce complex molecules.

Unsaturated hydrocarbons :

  • The unsaturated hydrocarbons containing one or more triple bonds are called alkynes. For example, ethyne (C₂H₂), propyne (C_3H_4), etc.
  • Alkynes have less number of hydrogen atoms as compared to alkanes and alkenes.
  • The first 3 members of Alkynes are gases, the next eight members are liquids and the remaining higher members are solids.
