On the basis of bonding, which of the following compounds has the highest boiling point? a. water. b. glucose. c. sodium chloride. d. alcohol

C. sodium chloride

Explanation:

Boiling point is temperature at which vapor pressure of the liquid becomes equal to external pressure (atmospheric) surrounding liquid.

On basis of bonding, the compound which has the highest boiling point is sodium chloride as it posses ionic bonding which is comprised of strong electrostatic bonds.

Water and alcohol are liquid and also, glucose has covalent bonding.

The melting points are shown below as:

Alcohol - 78.37 °C.

Glucose - 146 °C.

Water - 100°C.

Sodium chloride - 1413 °C.

Answer - C. sodium chloride

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
