The heat of vaporization of chloroform is to be calculated using the given data. Concept Introduction : Clausius-Clapeyron Equation is an expression that relates the vapor pressure of a liquid at two different temperatures with the enthalpy of vaporization of the liquid. The expression is given as ln P 2 P 1 = Δ H v a p R [ 1 T 1 − 1 T 2 ] P 1 = vapor pressure at temperature T 1 P 2 = vapor pressure at temperature T 2 Δ H v a p = Enthalpy of vaporization of the liquid R = Ideal gas constant = 8.314 J/Kmol

Question

Chapter 9, Problem 7QAP

(a)

Interpretation Introduction

Interpretation:

The heat of vaporization of chloroform is to be calculated using the given data.

Concept Introduction :

Clausius-Clapeyron Equation is an expression that relates the vapor pressure of a liquid at two different temperatures with the enthalpy of vaporization of the liquid. The expression is given as

lnP2P1=ΔHvapR[1T1−1T2]

P₁ = vapor pressure at temperature T₁

P₂ = vapor pressure at temperature T₂

ΔHvap = Enthalpy of vaporization of the liquid

R = Ideal gas constant = 8.314 J/Kmol

(b)

Interpretation Introduction

Interpretation:

The normal boiling point of chloroform under given conditions is to be calculated.

O Macmillan Learning Question 23 of 26 > Stacked Step 7: Check your work. Does your synthesis strategy give a substitution reaction with the expected regiochemistry and stereochemistry? Draw the expected product of the forward reaction. - - CN DMF MacBook Air Clearly show stereochemistry. Question

NH2 1. CH3–MgCl 2. H3O+ ? As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new C - C bond, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. This reaction will not make a product with a new C - C bond. Х ☐: C
