Potential Energy Curve

Questions

1) A triple bonded atom has ___ bond energy than a single bonded atom because ____.


a) higher, as the distance between the two atoms increases so does its energy

b) higher, the smaller distance between the two atoms in the triple bond requires more energy to break

c) lower, the smaller distance between the two atoms in the triple bond requires more energy to break

d) lower, as the distance between the two atoms increases so does its energy



2) If two atoms are closer to each other than the point of maximum attraction, they will suffer ___ because ___.


a) attraction, of electron shielding

b) attraction, their nuclei are too close
