2) Overlap integral: a measure of the extent of overlap of orbitals on neighboring
atoms.
3) The greater the overlap achieved (the larger integral), the stronger the bond
formed.
4) The relative overlapping powers of atomic orbitals have been calculated as
follows:
s: 1.00; p: 1.72; sp: 1.93; sp^2 : 1.99; sp^3 : 2.00- Sigma (σ) bond:
- A bond that is circularly symmetrical in cross section when viewed along the
bond axis. - All purely single bonds are sigma bonds.
- A bond that is circularly symmetrical in cross section when viewed along the
