Q. Match List I with List II. [table] List-I (Molecule) | List-II (Number and types of bond/s between two carbon atoms) ; A. ethane | I. one $\sigma$-bonds and two $\pi$-bonds ; B. ethene | II. two $\pi$-bonds ; C. carbon molecule, C$_2$ | III. one $\sigma$-bond ; D. ethyne | IV. one $\sigma$-bond and one $\pi$-bond [/table] Choose the correct answer from the options given below:
A) A-III, B-IV, C-II, D-I
B) A-III, B-IV, C-I, D-II
C) A-I, B-IV, C-II, D-III
D) A-IV, B-III, C-II, D-I
Explanation
[Solution by Claude - not from source] Ethane: one $\sigma$; ethene: $\sigma+\pi$; $C_2$ molecule: two $\pi$ bonds (MO picture); ethyne: $\sigma+2\pi$. Answer (1).
