A scientist calculated the energy required to break bonds in two unknown compounds, A and B. One compound has a covalent bond, and the other has an ionic bond. The table shows a record of these values. Bond Energy Compound ACompound B 769 kJ/mol432 kJ/mol Based on the table, which of the following statements is true?
a
Compound A is covalent because transfer of electrons makes relatively stronger bonds.
b
Compound B is covalent because sharing of electrons makes relatively weaker bonds.
c
Compound A is ionic because sharing of electrons makes relatively stronger bonds.
d
Compound B is ionic because transfer of electrons makes relatively weaker bonds.
