Draw curved arrows for each of the resonance contributors to indicate electron flow for the structure given below. Edit the reaction by drawing electron flow arrows where needed. Electron flow arrows should start on an atom or a bond and should end on an atom, bond, or location where a new bond should be created.

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
