Question

Match List I with List II.

List I (Molecule)		List II (Number and types of bond/s between two carbon atoms)
A.	ethane	I.	one σ-bond and two π-bonds
B.	ethene	II.	two π-bonds
C.	carbon molecule, C2	III.	one σ-bonds
D.	ethyne	IV.	one σ-bond and one π-bond

Choose the correct answer from the options given below:

• A. A-I, B-IV, C-II, D-III
• B. A-IV, B-III, C-II, D-I
• C. A-III, B-IV, C-II, D-I
• D. A-III, B-IV, C-I, D-II

Answer 1

The Correct Option is C

1. Ethane has a single $\sigma$-bond.
2. Ethene has one $\sigma$-bond and one $\pi$-bond.
3. $C_2$ has two $\pi$-bonds due to unique bonding.
4. Ethyne has one $\sigma$-bond and two $\pi$-bonds.
