MCQ
The bond that consist of an upper and a lower sharing of electron orbitals is called as :
  • ✓
    A $pi$ bond
  • B
    A sigma bond
  • C
    A hydrogen bond
  • D
    An ionic bond
✓

Answer

Correct option: A.
A $pi$ bond
The bond that consist of an upper and a lower sharing of electron orbitals is called as a $pi$ bond.
A pi bond is formed by lateral $($side ways$)$ overlap.
For example, two $\ce{2pz}$​ orbitals of two $C$ atoms laterally overlap to for pi bond in ethene $\mathrm{CH}_2=\mathrm{CH}_2$.
