Question

Identify the compound amongst the following of which 0.1 M aqueous solution has highest boiling point.

Options

• Glucose 

• Sodium chloride 

• Calcium chloride

• Ferric chloride

Answer 1

Ferric chloride

Explanation:

As all the compounds have same concentration, i. e. 0. 1 M. Thus, the compound that will break into the most parts has highest boiling point. 

Glucose (1 part, covalent; does not ionise)
Sodium chloride (1 Na, 1 Cl; ionises)

Calcium chloride (1Ca, 2Cl; ionises)
Ferric chloride (1Fe, 3Cl; ionises)
