Chemistry pretty urgent!!!!!!!

Chemical bonding question!

The partial Lewis structure that follows (Figure 1) 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 in order from left to right.

C=C-C(triple bond)C

Rank the carbon-carbon bonds in order of decreasing bond enthalpy.
Rank carbon-carbon bonds from highest bond enthalpy to lowest. To rank bonds as equivalent, overlap them.
