Answer 2

C2H2 has a triple bond.

• The carbon has a valency of four, and that's why it can form upto triple bonds with other atoms.
• In the C2H2 or acetylene, there is a triple bond between the two central carbon atoms.
• Rest of the two remaining bonds are occupied by the two hydrogen atoms by two single bonds.
• That's why, the correct answer of this question is C2H2.
