Different sigma and pi bond
Answers
Sigma bond
• Type of covalent bond.
• formed by the end to end overlap of
bonding orbitals aling the
Internuclear axis.
• called Head on overlap or Axial
overlap
Pi(π) bond
• The atomic orbital overlap in such a
way that their axes remain parallel
to each other and perpendicular to
the Internuclear axis.
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.
