The partial Lewis structure that follows is for a hydrocar-bon molecule. In the full Lewis structure, each carbon atom satisfies the octet rule, and there are no unshared elec-tron pairs in the molecule. The carbon—carbon bonds are labeled 1, 2, and 3. (a) How many hydrogen at-oms are in the molecule? (b) Rank the carbon–carbon bonds in order of increasing bond length. (c) Which carbon—carbon bond is the strongest one? [Sections 8.3 and 8.8]A C is double bonded (bond 1) right to C, which is single bonded (bond 2) right to C. That C is triple bonded (bond 3) right to C.
