Question

2-Pentene contain
a) 15 sigma and one pi bond
b) 14 sigma and one pi bond
c) 15sigma and two pi bond
d) 14 sigma and two pi bond ​

Answer 1

In 2-pentene there are 14 sigma bonds and one pi bond.

What are sigma and pi bonds?

• In organic chemistry, a sigma bond is formed as a result of the overlapping of two s orbitals along the axis of the bond.
• These sigma orbitals are also known as hybrid orbitals.
• It is represented by the symbol σ.
• On the contrary, pi (π) bonds are formed by the overlapping of p orbitals.
