Question

Ethene and ethyne differ in

• A. number of carbons
• B. number of bonds
• C. number of hydrogens
• D. Both (2) and (3)

Answer 1

The Correct Option is D

Correct answer: Both (2) and (3)

Explanation: 
- Ethene has the molecular formula $C_2H_4$ and contains a double bond between carbon atoms.
- Ethyne has the molecular formula $C_2H_2$ and contains a triple bond between carbon atoms.

So, the difference lies in:
- Number of bonds: Ethene has a double bond, while ethyne has a triple bond.
- Number of hydrogens: Ethene has 4 hydrogen atoms, while ethyne has only 2.

Therefore, the correct answer is Both (2) and (3).
