2. Consider propyne, \( \mathrm{H}_{3} \mathrm{CCCH} \). (a) Draw the Lewis structure. (b) What is the hybridization state of cach carbon? (c) What is the geometry around each carbon? Draw a 3D picture of the molecule using dashwedge symbols. (d) Draw the valence MOs for the C-C triple bond. What kinds of bonds are these? (c) Why is the C-C triple bond stronger than the \( \mathrm{C}-\mathrm{C} \) single bond? (f) Is it three times as strong? Why or why not?
