A when sulfuric acid is added to sirie, hydrager

irga5000 [103]

Sulfuric acid is prepared industrially by means of the response of water with sulfur trioxide which in turn is made by way of a chemical combination of sulfur dioxide and oxygen both by way of the touch system or the chamber system.

H2SO4 (l) H2O (g) + SO3 (g).

The reaction is highly exothermic as an enormous amount of heat is liberated.

The usual approach is to dilute the sulfur trioxide in sulphuric acid. This produces oleum. SO3 (g) + H2SO4 → H2S2O7 (1) Oleum can be in addition diluted in water to acquire concentrated sulphuric acid.

An acid catalyst is added to protonate the carbonyl carbon. How does this catalyze the response, robust acid catalysts catalyze the hydrolysis and transesterification of esters which enables the mechanism with a view to boom the electrophilicity of the carbonyl carbon to assist protonate the carbonyl oxygen.

One of the chair conformers of cis-1,3-dimethylcyclohexane is 5.4 kcal/mol less stable than the other. How much steric strain do

Karolina [17]

Answer:

See explanation

Explanation:

the Cis structure, we can have two possibilities. The methyl groups can go both in <u>axial positions</u> or both in <u>equatorial positions</u>. We have to remember that cis it means <u>"same orientation"</u>, so in the axial positions, both methyl groups go up. (Both have the same orientation). In the equatorial positions, both groups go down.

In the axial positions, we will have <u>more steric hindrance</u> because the groups are close to each other. Therefore, we will have <u>more energy</u> and the structure will be <u>less stable</u>. In the equatorial positions, we <u>dont have any steric hindrances</u>, so we will have <u>less energy and more stability</u>.
