MULTIPLE BONDS
Multiple
bonds and Hybridisation
multiple bond = s + n x p
(one e- pair) (one e- pair or more)
Multiple Bonds
- shorter & stronger than
single bonds
C-C 1.51Å C=C 1.33Å CºC 1.20Å
(N.B. = 1Å = 1x10-10 m, 1 nm =
1x10-9 m )
Bond
order = the no. of 2-electron covalent bonds
between atoms
1 =
single, 2 = double, 3 = triple
