If K _ b denote molal elevation constant of water, then boiling point of an aqueous solution containing 36 ~g glucose (molar mass =180 ) per dm ^3 is:

Step-by-step solution

Ionic character of metal halides decreases in the order MF > MCl > MBr > MI , where, M is a monovalent metal. Smaller the size of anion, greater is the ionic character (Fajan's rule). Therefore, MI has the lowest ionic character.
