Question

Which general formula represents the homologous series of hydrocarbons that includes the compound l-heptyne?

Answer 1

The general formula for the homologous series of hydrocarbons including l-heptyne is CnH2n-2. For l-heptyne, which has seven carbon atoms, the molecular formula is C7H12.

Step-by-step explanation:

The general formula that represents the homologous series of hydrocarbons including l-heptyne is CnH2n-2. In this formula, 'n' represents the number of carbon atoms in the hydrocarbon chain. For l-heptyne, which has seven carbon atoms, the molecular formula would be C7H2(7-2) = C7H12.

Answer 2

Answer:
General formula that represents the homologous series of hydrocarbons that includes the compound l-heptyne is CnH₂n-₂.

Step-by-step explanation:
1-Heptyne belongs to alkyne. As alkynes have a Hydrogen Deficiencey Index of 2, means if four hydrogen atoms are added to alkyne they will convert into alkanes with a general formula CnH₂n+₂. Therefore, any aliphatic carbon chain with a triple bond between two carbon atoms and general formula CnH₂n-₂ belongs to alkynes.
