Write the molecular formula of the third and the fifth members of the homologous series of carbon compounds represented by `C_(n)H_(2n-2)`.

Text Solution

Verified by Experts

The given compounds are alkynes. So, the first member of this homologous series should contain two carbon atoms bonded by a triple bond. Therefore, the third member should have four carbon atoms, and the fifth member should have six carbon atoms, i.e.,
for the third member, n = 4 and for the fifth member, n = 6
Then, Formula of the third member is `C_(4)H_(6)`. Formula of the fifth member is `C_(6)H_(10)`.
