D( )-Camphor is treated with 5-methoxytryptamine in the presence of sodium cyanoborohydride to generate a new molecule, as a sin

gle diastereomer, with molecular formula: C21H30N2O. Draw the starting materials, the imine intermediate, and the final product. (No mechanism is necessary). What is the rational for the reaction being diastereoselective (yielding a single diastereomer)

The reducing agent can approach the carbonyl face of camphor by forming a one carbon bridge (known as an exo attack) or a two carbon bridge (termed endo).

The two resultant stereoisomers are known as isoborneol and borneol (from exo attack) (from endo attack). Gas chromatography (GC) analysis may be used to calculate the ratio of each isomeric alcohol in the mixture. Unfortunately, IR analysis does not permit this.

The stereochemistry of the reaction is regulated in stiff cyclic compounds like camphor and norcamphor by protecting one side of the carbonyl group from the reagent's assault. The hydrogen atom is added to the endo side, creating the exo alcohol isoborneol, while the methyl groups on the one-carbon bridge of camphor screen the approach of the hydride from the "top" or exo side of the two-carbon bridge. You will be asked to guess the main isomeric alcohol created by the norcamphor hydride reduction later in the lab report.

1. 17.0 grams of xenon hexafluoride is in a solid container. How many milliliters of that gas
BlackZzzverrR [31]

Answer: The volume of gas is 3020 ml

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 821.4 torr =  1.08 atm     (760 torr = 1atm)

V = Volume of gas in L = ?

n = number of moles = \frac{\text {given mass}}{\text {Molar mass}}=\frac{17.0g}{245.28g/mol}=0.069mol

R = gas constant =0.0821Latm/Kmol

T =temperature =302.7^0C=(302.7+273)K=575.7K

V=\frac{nRT}{P}

V=\frac{0.069mol\times 0.0821Latm/K mol\times 575.7K}{1.08atm}=3.02L=3020ml

Thus volume of gas is 3020 ml

What is the frequency of infrared light of 1.0 × 10 m wavelength?
Anettt [7]
In order to find the answer you must plug in the information to the frequency equation, c=fv. C is the speed of light, 3.0 x 10^8. By plugging in the information you receive a frequency of 3.0 x 10^7 hz.

3/7 of a sum is Rs.1800. Find the sum​
STatiana [176]

Answer:

the sum is Rs 4,200

Explanation:

Given that

3 by 7 of the sum is $1,800

We need to find out the sum

So,

Here we assume the sum be x

So the following equation should be made

3 ÷ 7 × x = 1800

3x = 1800 × 7

x = (1800 × 7) ÷ 3

= Rs 4,200

Hence, the sum is Rs 4,200

The same would be considered and relevant

A gas has a volume of 200. mL at 350. mm Hg. What will its volume be if the pressure is changed to 555. mm Hg
mrs_skeptik [129]

Answer:

The final volume when pressure is changed is 126.1mL

Explanation:

Based on Boyle's law, in a gas the volume is inversely proportional to its pressure when temperature remains constant. The equation is:

P₁V₁ = P₂V₂

<em>Where P is pressure and V volume of 1, intial state and 2, final state.</em>

<em />

Computing the values of the problem:

350mmHg*200mL = 555mmHgV₂

126.1mmHg = V₂

<h3>The final volume when pressure is changed is 126.1mL</h3>
