Question 10 • *26-27 CFISD TX-Chemistry A CR

The incomplete table below shows selected properties of compounds that have ionic, covalent, or metallic bonds.RowBondElectrical conductivityLikely property1IonicYesHigh melting point2?Yes?3?No?Which information would best fill the blanks in row 3?

Answer
A
metallic bond and low melting point
B
metallic bond and high melting point
C
covalent bond and low melting point
D
covalent bond and high melting point

Explanation

Covalent compounds usually do not conduct electricity because they do not have freely moving charged particles. Many molecular covalent compounds also have low melting points because the forces between their molecules are relatively weak. So row 3 is best filled with “covalent bond and low melting point.”
