The tosylate of (2R,3S)-3-phenylbutan-2-ol undergoes an E2 elimination on treatment with sodium ethoxide. Draw the structure of

andrezito [222]

Answer:

(R)-but-3-en-2-ylbenzene

Explanation:

In this reaction, we have a very strong base (sodium ethoxide). This base, will remove a hydrogen producing a double bond. We know that the reaction occurs through an E2 mechanism, therefore, the hydrogen that is removed must have an angle of 180º with respect to the leaving group (the "OH"). This is known as the anti-periplanar configuration.

The hydrogen that has this configuration is the one that placed with the dashed bond (red hydrogen). In such a way, that the base will remove this hydrogen, the "OH" will leave the molecule and a double bond will be formed between the methyl and the carbon that was previously attached to the "OH", producing the molecule (R) -but-3- en-2-ylbenzene.

See figure 1

Comparing the mass of the nucleus with the mass of the protons and the mass of the neutrons refers to what?

DaniilM [7]

E) mass defect
This is so because the mass defect is the difference between the particles of the nucleous weight and the nucleous itself. According to the equation E=mc^2, the mass defect is related the the binding theory. In order to calculate the mass defect of an atom you need to add up the masses of each proton and each of neutron that are present in the nucleus and then you substract the actual mass of the nucleus from the combined mass.

HelpppA swamp is a wetland habitat that contains areas that are temporarily or permanently flooded. The Okefenokee Swamp is loca

FrozenT [24]

Wading birds live successfully in the swamp because : B) Their long legs allow them to wade in the waters without getting wet.

Explanation:

Wading birds are common habitat in swamp and muddy areas.

Some wadding birds are crane, egret, heron, sandpipers and ibis

Some characteristics of wading birds are:

long, thin legs. Also, they have large toes
long bills and long strong necks

Long legs of wadding birds allow them to walk easily in wetland without getting their feathers wet.

They live in water or near water, so their food are mainly aquatic insects, small amphibians and fishes.

Wading birds are also called shorebirds.

What is the mass in grams of 1.5*10^-3 mol of sodium

Nutka1998 [239]

The Formula to find the number of moles is:
Number of Moles = Mass/ Molar Mass

Which means that Mass = Number of Moles * Molar Mass

We know that Number of Moles of Sodium Na = $1.5*10^_{-3}$ moles
If you check the Periodic Table, Molar Mass of Sodium Na = 23g/mol

So, Mass = $1.5*10^_{-3} * 23$ = $3.45 * 10^{-2}$

So, the mass in grams of $1.5*10^_{-3}$ mol of Sodium is $3.45 * 10^{-2}$

Hope this Helps :)
