Interpretation: The reason for the lesser magnitude of the boiling point elevation than that of the freezing point depression must be interpreted.
Concept introduction: Colligative properties are the properties that depend on the number of particles present in the solution. Elevation in boiling point, depression in freezing point, lowering in vapor pressure and osmotic pressure are some common examples of colligative properties.

Answer to Problem 9.1CP
The boiling point elevation is less than the freezing point depression because it depends on the
Explanation of Solution
The elevation in the boiling point can be expressed as:
Whereas, the depression in the freezing point is:
Since the value of
The elevation in the boiling point and depression in the freezing point varies with

- The answer here says that F and K have a singlet and a doublet. The singlet and doublet are referring to the H's 1 carbon away from the carbon attached to the OH. Why don't the H's two carbons away, the ones on the cyclohexane ring, cause more peaks on the signal?arrow_forwardDraw the Birch Reduction for this aromatic compound and include electron withdrawing groups and electron donating groups. *See attachedarrow_forwardShow the correct sequence to connect the reagent to product. * see imagearrow_forward
