Question

On the basis of bonding, which of the following compounds has the highest boiling point? A) alcohol B) glucose C) water D) sodium chloride?

Answer 1

"Alcohol" is a very vague term because it refers to a very large class of compounds such as ethanol....etc.

The answer is Sodium Chloride (1400C).

Glucose does not have a boiling point because it evaporates and Water boils at 100C.

Hope I helped.

Answer 2

Answer : Option D) Sodium Chloride.

Explanation : Boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure surrounding the liquid.

On the basis of bonding, the compound which has highest boiling point is sodium chloride.

Alcohol are found to have boiling point approximately as 78.37 °C.

Glucose usually melts at 146 °C.

Water boils at 100°C.

Sodium chloride has boiling point 1413 °C.

So, it is easy to identify that NaCl (sodium chloride) has highest boiling point amongst the given choices.
