ANSWER:Step 1 of 3
(a)
The first element in any group can create pi bonds more easily. Because little atoms can approach each other more intimately, this trend is partially attributable to size. As a result, for the first member in each group, the overlap of orbitals, which results in the formation of pi bonds, is more effective.
