 Ethene and ethane have the same 

A. chemical properties

B. density

C. number of carbon atoms

D. general formula

Ethene (C₂H₄) and Ethane (C₂H₆) are both hydrocarbons.

Let’s check the options:

  • A. Chemical properties → No. Ethene is an alkene (unsaturated) while ethane is an alkane (saturated), so their chemical properties differ.

  • B. Density → Not necessarily the same.

  • C. Number of carbon atoms → Yes. Both contain 2 carbon atoms.

  • D. General formula → No.

    • Alkanes: CₙH₂ₙ₊₂ (ethane fits)

    • Alkenes: CₙH₂ₙ (ethene fits)

Correct answer: C. number of carbon atoms
