Question

Chapter 13, Problem 105E

Interpretation Introduction

Interpretation:

The temperature at which pure substance converts from liquid to solid at ATP

Find the freezing point of an aqueous solution.

Concept introduction:

Elevation in boiling point

∆T_b = ∆T_b = K_bm

Here,

∆T_b = Elevation in boiling point

K_b = Boiling point elevation constant

Depression in freezing point,

∆T_b = K_fm

Here,

∆T_b = Depression in freezing point

m = Molality

K_f = Freezing point depression constant of the solvent.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. . If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + T X O O лет-ле HO OH HO OH This transformation can't be done in one step.
