Question

(a) Give the names and structural formulae of the next two higher homologues of methane.
(b) The molecular formula of a hydrocarbon is C10H18. Name its homologous series.
(c) Select the hydrocarbons which are members of the same homologous series. Give the name of each series.
C5H10; C3H8; C6H10; C4H10; C7H12; C8H16

Answer 1

Answer:

a) C2H6 - ethane

C3H8 - propane

b)C10H18 - decyne -- Alkyne (homologous series)

c)Alkane - C3H8, C4H10

Alkene - C5H10, C8H16

Alkyne - C6H10, C7H14

thank u

Answer 2

Explanation:

(a) Ethane and propane are the next two higher homologues of methane.

Structural formulae of:

(b) $\mathrm{C}_{10} \mathrm{H}_{18}$ is the molecular formulae of a hydrocarbon. Its homologue series name is Alkyne whose molecular formula is $\mathrm{C}_{n} \mathrm{H}_{2 n-2}$.

(c) Alkanes: $\mathrm{C}_{3} \mathrm{H}_{5}, \mathrm{C}_{4} \mathrm{H}_{10}$.

    Alkynes: $\mathrm{C}_{5} \mathrm{H}_{10}, \mathrm{CaH}_{16}$.

    Alekenes: $\mathrm{C}_{6} \mathrm{H}_{10}, \mathrm{C}_{7} \mathrm{H}_{12}$.
