Draw the mechanism for the addition of methylmagnesium bromide to propanoyl chloride (CH3CH2COCl) to give 2-methyl-2-butanol.

Ghella [55]

Answer:

Reaction mechanism has been given below

Explanation:

Propanoyl chloride contains an electrophilic carbonyl center to give nucleophilic acyl substitution reaction by removing Cl group with a strong nucleophile like methylmagnesium bromide.
Two equivalent of methyl magnesium bromide react with cabonyl center followed by protonation of negatively charged oxygen atom gives 2-methyl-2-butanol.
In the first step, nucleophilic acyl substituion occurs. In the second step, nucleophilic addition occurs. In the third step, protonation occurs.
Reaction mechanism has been shown below.

ammonium bromide reacts with copper(i) sulfate in aqueous solution to form a solid precipitate. what is the net ionic equation f

sukhopar [10]

Answer:

$Br^-(aq)+Cu^+(aq)\rightarrow CuBr(s)$

Explanation:

Hello,

In this case, the molecular chemical reaction is written as:

$2NH_4Br(aq)+Cu_2S(aq)\rightarrow 2CuBr(s)+(NH_4)_2SO_4(aq)$

In such a way, considering the net ionic notation and the solid yielded copper (I) bromide, we write:

$2NH_4^+(aq)+Br^-(aq)+Cu^+(aq)+SO_4^{2-}(aq)\rightarrow CuBr(s)+NH_4^+(aq)+SO_4^{2-}(aq)$

Whereas ammonium and sulfate ions are spectator ions, therefore the net ionic equation is:

$Br^-(aq)+Cu^+(aq)\rightarrow CuBr(s)$

Regards.

What is the mass of 15 moles of carbon atoms? Round your answer to the nearest hundredth

Georgia [21]

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass. More commonly written for this application as: where, is the molar mass of the substance.

Hope this helped

The ______ force is equal to the weight of the fluid displaced by an object. gravitational friction buoyant

Tju [1.3M]

Buoyant

Buoyancy is the ability to float in fluids.
Gravity is the force of all objects attracted to one.
Friction is the force caused when two objects rub against each other causing them to slow

<span>Archimedes principle explains that the magnitude of that force is proportional to the difference in the pressure between the top and the bottom of the column, and</span> is also equivalent to the weight of the fluid that would otherwise occupy the column, i.e. the displaced fluid.
