We are asked to rank the carbon-carbon bonds in order of decreasing bond length.
The strength of the bond between atoms increases as the number of electron pairs in the bond increases.
The number of electron pairs that hold two atoms together is called the Bond order.
For a single bond (Bond 2), the bond order is one.
For a double bond (Bond 1), the bond order is two and for a triple bond (Bond 3) is three.
The partial Lewis structure that follows is for a hydrocarbon molecule. In the full Lewis structure, each carbon atom satisfies the octet rule, and there are no unshared electron pairs in the molecule. The carbon-carbon bonds are labeled 1, 2, and 3.
Rank the carbon-carbon bonds in order of decreasing bond length.
