Unformatted text preview: PI ( # ) MO or bond, from sideways overlap, preserves nodal plane, used in multiple bonds. HYBRID ORBITAL = linear combination of s and p atomic orbitals on same atom ! hybrid = c s ! s + c p ! p (+ c p ' ! p' + …) In a hybrid orbital P ( x , y , z ) is increased on one side and reduced on other, so gives better overlap than s or p alone, where half the atom's electron density is "wasted". (bonding MO) ! MO = c A ! hybrid on A + c B ! hybrid on B Conservation of orbitals: number of hybrids = number of s and p orbitals used 2 sp hybrids from one s and one p 3 sp 2 hybrids from one s and two p 4 sp 3 hybrids from one s and three p Hybridization = sp 3-N # = sp 3-N double-2 N triple...
