Question
Chapter 4, Problem 69P
Interpretation Introduction
Interpretation:
In the given species (atoms or molecules) those are free radicals have to identify.
Concept introduction:
The free radicals are odd electron molecules which are generally electrically neutral (some ionic free radicals are also known). The free radicals possess addition properties and are extremely reactive. The stable free radicals are stabilized due to the resonance. These are paramagnetic in nature, contains a permanent magnetic moment due to the presence of the unpaired electron. This property is used to detect the presence of free radical.
Correct answer:
Among the given molecules only nitrogen dioxide 
is a free radical.

The following is a total synthesis of the pheromone of the western pine beetle. Such
syntheses are interesting both because of the organic chemistry, and because of the possibility of
using species specific insecticides, rather than broad band insecticides. Provide the reagents for
each step. There is some chemistry from our most recent chapter in this synthesis, but other
steps are review from earlier chapters. (8 points)

The last step is just nucleophilic addition reactions, taking the
ketone to an acetal, intramolecularly. But
it is hard to visualize the three dimensional shape as
it occurs.

- 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,…arrow_forward1.
