Solution Summary: The author explains the molality or molarity dependent on temperature in freezing-point depression and boiling point elevation calculations.
Interpretation: The molality or molarity dependent on temperature is should be explained and reason for the usage of molality in freezing-point depression and boiling point elevation calculations are explained.
Concept introduction:
Elevation of boiling point:
The boiling point of the solution is increases when the solute is dissolved in the solvent are called Elevation of boiling point. It is one of the colligative Properties thus,
ΔT=iKbmsolute......(1)ΔT is boiling-point elevationKbismolal boiling-point elevation constantmis molality of the soluteiisthevan't Hoff factor
Depression in freezing point:
The freezing point the solution is decreases when the solute is dissolved in the solvent is called Elevation of boiling point. it is one of the colligative Properties thus
ΔT=iKfmsolute......(2)ΔT is boiling-point elevationKfismolal freezing-point depression constantmis molality of the soluteiisthevan't Hoff factor
Molarity:
The gram moles of solute in liter of solvent is called molarity and in is the term of concentration.
Molarity=solutemassgsolventvolumeL
Molality:
The gram moles of solute in kilogram of solvent is called molality and in is the term of concentration.
First image: I have to show the mecanism for the reaction on the left, where the alcohol A is added fast in one portion
Second image: I have to show the mecanism of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary
First image: I have to explain why the molecule C is never formed in those conditions.
Second image: I have to propose a synthesis for the lactone A
