Chapter 9, Problem 9.58P
Interpretation Introduction

Interpretation:

Which solvent, ethanol or dimethyl sulfoxide, would be better for carrying out the given reaction is to be determined.

Concept introduction:

Polar aprotic solvents favor SN2/E2 reactions. In SN2 reaction, the nucleophile starts forming a bond with the electrophilic carbon before the leaving group has departed. In E2 reaction, the attacking species acts as a base, removing an acidic proton. In general, strong negatively charged nucleophiles (or bases) work best in these reactions. Negatively charged species are strongly solvated by protic solvents, reducing their strength as a nucleophile or a base. Aprotic solvents do not effectively solvate the nucleophile/base, and therefore, work better.

Polar protic solvents favor SN1/E1 reactions. Both reactions start the same way. The leaving group departs or the base extracts an acidic proton to form a carbocation in the first step. The nucleophile/base has not participated in this step. A protic solvent will therefore promote an SN1/E1 reaction in two ways; by stabilizing the carbocation as well as the nucleophile/base.

Ideal Gas Law Practice Name If you need a refresher on Ideal Gas Law, go back to your Ideal Gas Law Reading Assignment from last week! On all of the following, you'll need to make sure to convert pressures to atm and convert temperatures to Kelvin in order to be able to use the R gas constant on your equation sheet! Given: Ideal Gas Law = then P= pressure V = volume R= ideal gas consent PV=nRT namount of substance n=PV/TR P=nRT/V I = temperature V=nRT/P T=PV/nR R=PV/nT 1. What pressure is required to contain 0.023 moles of nitrogen gas in a 4.2 L container at a temperature of 20.°C? 2. Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0 L. What temperature must be maintained on 0.500 moles of this gas in order to maintain this pressure? Express the temperature in degrees Celsius. 3. How many moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100. °C? After determining the number of moles,…
