The first step in the formation of all three products is the loss of the ots leaving group to give a carbocation intermediate. t
lina2011 [118]

The carbocation stabilized by resonance structure and thereby lowers the energy of the carbocation, hydrogen will add to the carbon in the double bond that produces delocalization of electrons.

<h3>What is carbocation?</h3>

A carbocation is a molecule in which a carbon atom has a positive charge and three bonds.

In general, electrons are stabilized by delocalization. The stabilization energy engendered by delocalization over more than two atoms is called the resonance stabilization energy or simply the resonance energy. The greater the extent of electron delocalization the greater the resonance stabilization.

VladimirAG [237]

Answer:

In sea water;

The salt is the solute while the water is the solvent

In soda water;

The water is the solvent, the carbon dioxide is the solute

In air;

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes

Explanation:

A solution is a homogeneous mixture of two or more substances which includes a solvent and a solute. A solute in a solution is dissolved in the solvent of the solution.

Therefore, the solvent is the major part of a solution as it takes in the solvent to form the solution.

In sea water, a solution with a high concentration of salts

The salt is the solute while the water is the solvent

In soda water,  which is a mixture of CO₂ in water,

Here we have in the soda solution, the water is the solvent while the carbon dioxide is the solute

The water is the solvent, the carbon dioxide is the solute

Air a solution made up by a mixture of Nitrogen 78%, oxygen 21%, and small amount of water carbon dioxide and argon

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes.
