Question

The normal electron configuration for ethyne (acetylene) is

• A. $H:C::C:H$
• B. $H:C:C:H$
• C. $H^{\cdot }C::::C^{\cdot }H$
• D. $H:C:::C:H$
• E. $H::C:C::H$

Answer 1

The correct option is D $H:C:::C:H$

Carbon consists of 4 electron it valence shell and hydrogen has 1 electron in its valence shell so they form bond in such a manner such that their octet is completed.
