Represent the bonding in each molecule or ion by drawing the orbitals (hybridized and unhybridized) of each atom in the bond. Label the σ and π bonds and label each bond by the orbitals that it is made from. For instance, the C–H bond in CH4 would be made from the overlap of: C (sp3) – H (1 s). You may draw the hybridized sigma orbitals as sticks and the unhybridized p-orbitals as lobes for clairity and ease. a. HONO b. CH3 CCH c. C3 H4 d. C2 O4 2-
