Chemistry Question on Chemical bonding and molecular structure
Number of σ and π bonds present in ethylene molecule is respectively :
A
3 and 1
B
5 and 2
C
4 and 1
D
5 and 1
Answer
5 and 1
Explanation
Solution
Ethylene (C 2H4) has the following bonding:
- Each carbon is sp2 hybridized, forming three σ bonds (two with hydrogen and one with the other carbon).
- There is one π bond between the two carbons formed by the overlap of unhybridized p orbitals.
Thus, ethylene has:
5 σ bonds and 1 π bond.
