NEET Chemistry Molecular Orbital Theory MCQ Question
Which combination of statements about the bonding in C2H2 and C2H4 is correct?
C2H2 has one sigma bond and two pi bonds, while C2H4 has one sigma bond and one pi bond.
C2H2 contains sp2 hybridized carbon atoms, while C2H4 contains sp hybridized carbon atoms.
C2H2 forms a triple bond, while C2H4 forms a double bond between carbon atoms.
Both C2H2 and C2H4 contain only sigma bonds between carbon atoms.
Correct Answer
Detailed Explanation
C2H2 (ethyne) has a triple bond composed of one sigma bond and two pi bonds, while C2H4 (ethylene) has a double bond consisting of one sigma bond and one pi bond, as detailed in the molecular orbital theory.
