Document Summary
Common bond dipole moments i. ii. iii. iv. v. vi. vii. viii. ix. x. xi. xii. Molecular dipole moment is the vector sum of all the bonds in the molecule. Use dots for all the valence electrons including those in bonds b. Uses lines to represent pairs of electrons in bonds. Still uses dots for the lone pairs c. Use groups to show backbone and sidechains d. Bond line but no carbons or hydrogens are specifically included. When molecular orbitals overlap constructively it is a bonding orbital. When molecular orbitals overlap destructively it is an antibonding orbital. Electrons are always in lower energy which is the constructive. Moving of electrons in a molecule a. b. c. d. e. f. g. Shifts between double bonds and lone pairs (delocalized electrons) Not all are equal most stable are seen the most. Use curved arrows to show movement of electrons a. b. c. Lone pair to an adjacent bond a. b. c.
