Which of the following belongs to homologous series of alkenes?

Correct option is D

Correct Answer: D) C₃H₆

Explanation:

A homologous series is a group of organic compounds with similar structures, differing by a constant unit (CH₂), and possessing the same functional group. Alkenes are hydrocarbons with at least one double bond, and their general formula is CₙH₂ₙ.

Analyzing the options:

• C₃H₆ (D) fits the general formula for alkenes (CₙH₂ₙ) because:
• n = 3 → H = 2n = 6 → Formula is C₃H₆.
• It is propene, an alkene with a single double bond.

Information Booster:

•  Alkenes are unsaturated hydrocarbons with at least one carbon-carbon double bond.
  
• They are highly reactive due to the presence of the double bond.
  
•  The simplest alkene is ethene (C₂H₄).
  
•  Members of the alkene homologous series follow the formula CₙH₂ₙ.
  
•  Alkenes are widely used in the petrochemical industry for making plastics, detergents, and synthetic rubber.

Additional Knowledge:

• (C₃H₄): Does not belong to the alkene series as it does not fit the formula CₙH₂ₙ. It could be a compound with a triple bond (alkyne).
• (C₃H₈):  Belongs to the alkane series (CₙH₂ₙ₊₂) as it contains only single bonds.
• (C₅H₁₂): This is an alkane (CₙH₂ₙ₊₂), not an alkene.
