Which of the following shows linear structure

Options

(a) acetylene
(b) CCl₄
(c) ethane
(d) ethene

Correct Answer:

acetylene

Explanation:

Acetylene (H -C ≡ CH) has linear structure.In acetylene, each carbon used its 2s, and one of its 2p orbitals to undergo sp hybridization. The two hybrid orbitals are inclined to each other at an angle of 180⁰.
