Resonance structures have two or more possible electron structures. Often, they are showed with dotted lines or two+ structures with an arrow between them. The electrons distribute themselves evenly between both configurations (probability-wise) so that what we end up is roughly an "average".

Electron-deficient molecules represent the second violation to the octet rule. These stable compounds have less than eight electrons around an atom in the molecule. The most common examples are the covalent compounds of beryllium and boron. Hope this will help u

It is because of the reason that Hydrogen peroxide when kept for long time will under go auto-oxidation and releases oxygen and water. This process takes place slowly. 2H2O2 → 2H2O + O2

Yogita Ingle 6 years, 11 months ago

H2O2 is very unstable and highly reactive. Its vapours are explosive in nature at normal temperature and pressures. It decomposes easily and can lead to hazardous reactions. Hence very high care should be taken for the long time storage of H2O2.
It should be stored in cool, dry, well-ventilated area and away from any flammable or combustible substances. It should be stored in non-reactive containers. As it breaks down quickly when exposed to light, it should be stored in an opaque container (brown bottles).

When sodium carbonate dissolves in water it dissociates into two sodium (Na+) ions and a carbonate (CO3–2) ion;- Na2CO3 (s) —-> 2 Na+(aq) + CO3–2(aq) The carbonate ion is able to remove protons (H+) from water to form bicarbonate ions and hydroxide ions. Hence it is the conjugate base of the bicarbonate ion; CO3–2(aq) + H2O(l) ←-> HCO3-(aq) + OH-(aq) The overall increase in OH- ions due to these reactions results in an increase in the pH of the solution, and cause it to become alkaline.

Radical, also called Free Radicalmolecule that contains at least one unpaired electron. Most molecules contain even numbers of electrons, and the covalent chemical bonds holding the atoms together within a molecule normally consist of pairs of electrons jointly shared by the atoms linked by the bond. Hope this will help u

Kaavya Singh 6 years, 11 months ago

Free radical is an atom or group of atoms having an unpaired electron. For example: A-B -> A• + B• In this example A• and B• are free radicals.

Yogita Ingle 6 years, 11 months ago

A free radical reaction is any chemical reaction which involves free radicals.

In the mechanism of a chemical reaction if the attacking reagent is free radical then that reaction mechanism is called free radical mechanism.

Example: Halogination of alkanes

Organic Chemistry It is a branch of chemistry which deals with the study of carbon-based compounds. It mainly applies to the study of the behavior, characteristics, compositions and the properties of the organic compounds. It is also known as The Chemistry of Life.
Inorganic Chemistry A branch of chemistry that deals with the study of metals and gaseous matter or materials which do not contain carbon as an element in it is called Inorganic chemistry. It is opposite side of Organic Chemistry.
Physical Chemistry The combined study of using physics and chemistry to explain chemical systems is called Physical chemistry. This branch relates to the physical properties along with the structure of matter and energy. The sub-branches coming under this field are quantum physics and thermodynamics.

Postulate of vsepr are:- 1-The shape of any molecule can be explained by the repulsion between all the electron pairs that are present in the valence shell. 2- The repulsion between two lone pairs is greater than the repulsion between a lone pair and a bond pair. Presence of a lone pair on the central atom causes slight distortion of the bond angles from their ideal values. 3- The electronegativity difference between the central atom and the other atoms determines the magnitude of repulsion between the bonding pair of electrons.

Postulates of Valence Bond Theory

  • The overlapping of two half-filled valence orbitals of two different atoms results in the formation of the covalent bond. The overlapping causes the electron density between two bonded atoms to increase. This gives the property of stability to the molecule.
  • In case the atomic orbitals possess more than one unpaired electron, more than one bond can be formed and electrons paired in the valence shell cannot take part in such a bond formation.
  • A covalent bond is directional. Such a bond is also parallel to the region of overlapping atomic orbitals.
  • Based on the pattern of overlapping, there are two types of covalent bonds: sigma bond and a pi bond. The covalent bond formed by sidewise overlapping of atomic orbitals is known as pi bond whereas the bond formed by overlapping of atomic orbital along the inter nucleus axis is known as a sigma bond.

1.If the centre atom is surrounded by only bond pair,the structure and shape will be same. 2.If the centre atom is surrounded by both bond pair and lone pair the structure and shape will not be same.3.Lone pair and lone pair repulsion having bond closing tendency while bond pair -bond pair having opening tendency.

Polarizing power can be defined as the ability of a cation to attract the electron cloud towards itself. Polarising power is proportional to charge/size. If the size of the cation is small, it will have more charge density and hence its polarising power increases whereas in anions with increase in its size polarisability increases. Also, higher the charge on a cation more is its polarizing power while higher the charge of an anion more is its polarisability.
The region of space around the nucleus which describes the probability of finding an electron of given energy in terms of dots is called an electron cloud.

Sanidhya Jadaun? 6 years, 11 months ago

cyclohexanone is wrong . Because if the C of C=O is included in the parent chain , then it is cyclohexanone. But now parent chain is of 6 C atoms and substituent group is C=O.

Benzene is the archetypical aromatic compound. It is planar, bond angles=120º, all carbon atoms in the ring are sp2 hybridized, and the pi-orbitals are occupied by 6 electrons. The aromatic heterocycle pyridine is similar to benzene, and is often used as a weak base for scavenging protons.
