Boiling point chemistry
Web1. number of carbons (increase in number of carbons, and hence molecular weight, increases BP) 2. Like you said, surface area. (increase in SA results increase in BP) 3. The strength of IMF. So I believe, that because nonane has more number of carbons AND more surface area, that's TWO factors that makes it have higher BP. WebSince NaCl dissociates into 2 ions, the Van’t Hoff factor for this compound is 2. Therefore, the boiling point elevation (ΔT b) can be calculated as follows: ΔT b = 2 × (0.52 o C/molal) × (0.619 molal) = 0.643 o C. Boiling point of the solution = boiling point of pure solvent + boiling point elevation. = 100 o C + 0.643 o C = 100.643 o C.
