question 16 of 25\nwhich molecule most likely has the greatest amount of stored energy in its bonds?\na. na - cl\nb. o = c = o\nc. h - o - h\nd. fe - o

Answer

Explanation:

Step1: Recall bond - energy concept

The greater the bond - energy, the more energy is stored in the bond. Different types of bonds have different bond - energies.

Step2: Analyze each option

  • For A. $Na - Cl$: It is an ionic bond. Ionic bonds have relatively high bond - energies, but we need to compare with others.
  • For B. $O = C = O$ (carbon - dioxide): It has double bonds. Double bonds have high bond - energies. The $C = O$ bond energy is approximately 799 kJ/mol.
  • For C. $H - O - H$ (water): The $O - H$ bond energy is approximately 463 kJ/mol.
  • For D. $Fe - O$: It is an ionic bond in iron oxides. The bond - energy of $Fe - O$ is not as high as the $C = O$ double bond in $CO_2$.

Answer:

B. O=C=O
