boiling point of 1 m solution of sugar, glucose, urea, sodium chloride, aluminium chloride, barium chloride

Dear Raksha,

The question seems to be incomplete but in my opinion you want to ask the order of elevation in boiling point of 1 m solution of the mentioned compounds. So I am providing you the increasing order of elevation in boiling point of the following compounds.

Elevation in boiling point is directly depends upon the number of ions which is going to produced when that compound gets dissolved in water. As the number of ions in solution increases elevation in boiling point increases. The number of ions produced per molecule of compound is called as van't hoff factor and is represented by i.

The number of ions produced by 1 m of sugar, glucose and urea are one. They does not dissociates into ions because they exist in molecular form in water. So they all will have same and least boiling point.

NaCl, Barium chloride and aluminum chloride will produce 2, 3 and 4 ions respectively.

Therefore the increasing order of boiling point of 1 m solution will be as follows

$Urea=Sugar=Glu\cos e<NaCl<BaC{l}_2<AlC{l}_3$
