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

Explain how to calculate the density of a regular shaped object such as a rectangular box.

belka [17]

The density of a regular shaped object such as a rectangular box is calculated as thus:

The amount of matter is its mass, and the space it takes up is its volume.

So therefore, to calculate the density of an object such as the a regular shaped one like a rectangular box;

Its density = mass / volume.

<h3>Derived quantities</h3>

These are physical quantities which are obtained from fundamental quantities. I'm order words, derived quantities are quantities which are obtained from the combination of of fundamental quantities either by addition, division or multiplication

Some few examples of derived quantities are as follows:

Density

Velocity
Upthrust
Volume
Acceleration

So therefore, the density of a regular shaped object such as a rectangular box is calculated as thus:

The amount of matter is its mass, and the space it takes up is its volume.

So therefore, to calculate the density of an object such as the a regular shaped one like a rectangular box;

Its density = mass / volume.

What happens to the half-life and mass of reactants broken down during a nuclear decay reaction?

sveta [45]

A) The half-life of reactants in a nuclear decay reaction remains constant over time, but the mass of reactants that are consumed decreases

Explanation:

The rate at which elements decays radioactively is directly proportional to the number of atoms present in it. This is a simple first-order kinetics.

The half-life of a radioactive element is the time taken for half of the radioactive nuclei to disintegrates.

The shorter the half life, the larger the decay constant and the faster the decay process. If a radioactive decay is fast, the mass of the reactants will decrease significantly with time thereby producing more of the daughter isotopes.

The reactant in a radioactive decay are the parent isotopes. The products are the daughter isotopes.
