what is the basis for the classification of organic compounds?

Answer:

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Answer:

Nonmetals are further to the right on the periodic table, and have high ionization energies and high electron affinities, so they gain electrons relatively easily, and lose them with difficulty.

Explanation:

They also have a larger number of valence electrons, and are already close to having a complete octet of eight electrons.

Periodic table is divided as metals, non metals, noble gases and semiconductors. Among these nonmetals tend to have high electron affinities because of small size and high effective nuclear charge.

Non metals are the element that have property to gain electron. When any element gain electron then element attain negative charge and that element is called anion.

As we go from left to right in periodic table, the size of element decreases as number of electrons keep on adding electrons in the same shell . As the number of electrons increases, the number of proton in the nucleus also increases. Due to this, the hold of nucleus on the outermost proton increases and the size decreases. Due to this, the ionization energy increases and hence the power to gain electron increases.

Therefore, nonmetals tend to have high electron affinities because of small size and high effective nuclear charge.

Pure water is at 7, and the bases are above 7 and the acids are below 7.

The pH of the solution that is classified as a weak base is 10. Details about weak bases can be found below.

pH of a solution refers to the degree of acidity or alkalinity of that solution.

The pH scale reads from 1 - 14 where the following applies:

A weak base will have a pH close to neutral, therefore, the pH of the solution that is classified as a weak base is 10.

The motion of particle of bromine in liquid is less as compared to the gaseous phase.

Entropy is defined as the motion of particle how randomly a particle move.

Entropy is also defined as the no. of particle per unit surface area.

In liquid phase, the number of particle per unit surface area is greater. The particle are closer with each other through the intermolecular force of attraction. Due to which randomness of particle decreases. Hence motion of particles decreases.

In gaseous phase, the number of particle per unit surface area is lesser. The particle are less closer with each other and have less intermolecular force of attraction. Due to which randomness of particle increases. Hence, motion of particles increases.

Thus, we concluded that the motion of particle of bromine in liquid is less as compared to the gaseous phase.

Answer:

7 moles of NaOH will produced.

Explanation:

Given data:

Number of moles of sodium oxide = 3.5 mol

Number of moles of sodium hydroxide produced = ?

Solution:

Chemical equation:

Na₂O + H₂O      →     2NaOH

Now we will compare the moles of sodium oxide with sodium hydroxide.

                 Na₂O            :         NaOH      

                    1                 :             2

Explanation:

Cumene is the end result of the reaction between benzene and 2-chloropropane when aluminum chloride is present.

Alkylation serves as an example of replacing the "alkyl group on the aromatic ring." In the alkylation reaction, the term "alkyl halides" is important. The "Lewis acid" suggested an alkylation catalyst.

Cumene is produced when the benzene molecule interacts with 2-chloropropane in the presence of aluminum chloride. By losing chlorine, the 2-chloropropane combines with aluminum chloride to produce a carbocation. Cumene is produced by further attacking benzene and protonating it.

Explanation:

need thanks and make me brainiest if it helps you

There will be two atoms of phosphorus in the 1.75 mol of calcium phosphate.

Atoms are the smallest unit of matter. In a chemical reaction, the number of atoms shows the quantity of an element in the compound or reaction. Phosphorus is a chemical element that is preset in the periodic table.

In calcium phosphate, Ca3(PO4)2, the number of atoms can be calculated by counting the number of moles that is given in the equation.

The number of atoms of calcium is 3, and the number of phosphorus atoms is 2.

Now given the 1.75 mol of calcium phosphate, so the number of atoms of phosphorus will be the same in any number of moles of calcium phosphate. So there will be 2 atoms of phosphorus in the given equation.

Thus, the number of atoms is two.

Answer:

Group 1 metals or the alkali metals

Explanation:

The group 1 elements are all metals except for hydrogen, the first element in the group. Group 1 metals have one valence electron in their outermost shell. The metallic character increases as one goes down the group.

The metallic character of an element is determined by how readily it loses electrons. Elements that lose electrons most easily have the greatest metallic character. Group 1 metals have the greatest metallic character due to the ease with which they donate or lose their one valence electron. As the atomic radius increases on going down the group, their metallic character increases. Also, due to screening effect of the inner electrons on the valence electron from the positive nuclear charge of the nucleus, metallic property increases on going down the group.

Now we will compare the moles of hydrogen and nitrogen.

                  H₂         :        N₂

                    3         :          1

                  4.5        :          1/3×4.5 = 1.5 mol

Thus, 1.5 moles of nitrogen are required to react with hydrogen.
