We see below that 3-methyl-3-hexanol can be synthesized from the reaction of 2-pentanone with ethylmagnesium bromide. There is a
netineya [11]

Answer:

See explanation below

Explanation:

Ok, the first picture is your exercise. We have one type of reaction to form the 3-methyl-3-hexanol.

Now, according to the question, you want another form to get the 3-methyl-3-hexanol. In this case, the easiest way to do this, is using a ketone with the 6 carbons, and the grignard reagent to use should have the methyl group. Now, in which carbon should the carbonile group be? well, as the final product has the OH group in carbon 3, then the reaction is taking place there. So the reactants would be the hexan- 3 - one and the methyl magnesium bromide.

The second picture, you'll see the reactants and final product.

Hope this helps

Rubidium Rb
Fantom [35]

Answer:

  • Rubidium Rb was discovered in 1861
  • It was discovered by the German chemist Robert Wilhelm Bunsen and the German physicist Gustav-Robert Kirchoff

Explanation:

Rubidium was discovered by the German chemists Robert Bunsen and Gustav Kirchhoff in 1861 while analyzing samples of the mineral lepidolite with a device called a spectroscope. The sample produced a set of deep red spectral lines they had never seen before. Bunsen was eventually able to isolate samples of rubidium metal. Today, most rubidium is obtained as a byproduct of refining lithium.

Answer:

c, atoms

Explanation:

Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms. The atoms of certain elements readily bond with other atoms to form molecules. Examples of such elements are oxygen and chlorine.
