Distinguish between a sigma and a pi bond.
Answers
Answer:
Sigma and pi bonds are types of covalent bonds that differ in the overlapping of atomic orbitals. Covalent bonds are formed by the overlapping of atomic orbitals. Sigma bonds are a result of the head-to-head overlapping of atomic orbitals whereas pi bonds are formed by the lateral overlap of two atomic orbitals.Jan 5, 2020
Answer:
sigma bond:
➡️A sigma bond is formed by the axial overlap of orbitals.
➡️extent of overlapping is more hence the bond is stronger.
➡️A sigma bond involves overlap pf s-s ,s-p, p-p orbitals.
➡️free rotation of atoms is possible across a sigma bond.
pi bond:
➡️A pi bond is formed by the side ways overlap of orbitals.
➡️ extent of overlaping is less hence the bond is weak.
➡️A pi bond involves the overlap of p orbitals only.
➡️ there is no free rotation of atoms across a pi bond.
