Quick and easy way to learn the organic nomenclature (with video).

Most of the students find it difficult to learn and apply the knowledge related to the organic nomenclature. Here in this post you simply need to memorise the following table and after that there are a few steps related to that.

What is the order of reactivity of halogen and alkyl groups in the dehydrohalogenation of alkyl halides to give alkenes ?

The reactivity of halogens :- The above order in case of halogens is due to the fact that the size of fluorine is small which makes a strong bond with carbon of alkyl group, thus makes it difficult to break. But on the other hand in case of Iodine the bond between Iodine and Carbon

what is the difference between mechanical and chemical digestion ?

Mechanical digestion :- In this type of digestion the food is broken down into simple particles in mechanical way , like chewing in mouth by teeth and churning of food in stomach by the muscular movements of the smooth muscles of stomach walls. Chemical digestion :- In this type of digestion the complex molecules of

how we can prepare carboxylic acid (benzoic acid) from acyl halides and acid anhydrides (benzoic anhydride)

Preparation of carboxylic acids from acyl halides is a simple method in which the acid chloride or halide is hydrolysed to give carboxylic acids. The general reaction and examples are given below.. The hydroxyl group (OH group) present in water replaces the halide atom and thus forms the carboxylic acid. Various acids are formed by

The SN2 mechanism

This is a type of reaction mechanism that is seen in case of nucleophillic substitution reactions. It is BIMOLECULAR NUCLEOPHILLIC SUBSTITUTION mechanism. In this kind of mechanism two molecules decide the rate of reaction, so it is BIMOLECULAR mechanism. The whole mechanism proceeds through a single step. That concerted step involves the bond breaking and

Stobbe reaction and its Mechanism

It is a type of condensation reaction that involves the condensation of an aldehyde or ketone with succinic ester in the presence of sodium ethoxide or Potassium ethoxide to yield unsaturated ester acid . The complete reaction is as below. The mechanism involves 3 steps , and firstly the succinate is treated with base to

How the age of mummies , dead bodies and fossils is calculated?

The aging of different organisms is mainly calculated by the special technique called the Radiocarbon dating. In this technique the age of any specimen is calculated on the basis of the present amount of an isotope of a particular element. Isotopes are the atoms of an element that have same atomic number but different atomic

Why does copper turns green on exposure to air ?

This happens because of corrosion of copper , as the copper is exposed to air it reacts slowly with water from the moisture present in air, carbondioxide and oxygen. And the product formed is a mixture of copper hydroxide and copper carbonate as shown below.

How many lone pairs of electrons are on the S atom in sulphur tetra floride (SF4) ?

In case of SF4 there are 6 electrons in the outermost shell of Sulphur, out of these 6 electrons, 4 are utilized in bonding with fluorine and thus two unshared electrons are there. Which leads to the lone pair as shown below. Contribute to make this site more informative.

What is hydrogen bond? How does an intermolecular hydrogen bond differ from intramolecular hydrogen bond ?

Actually the hydrogen bond is simply a type of attraction which is caused by the the electronegativity difference between hydrogen and highly electronegative element like oxygen carbon nitrogen and fluorine. Intermolecular hydrogen bonding takes place between two molecules having hydrogen and electronegative element. Hydrogen is attracted by the electronegative element of another molecule for example

What are Colligative properties ?

Actually the word co-ligative itself reveals that (“co” means each other and “ligative” means related) These are the properties which are related to each other. The colligative properties are those properties that depend on the number of solute particles in a solution or a mixture. “These properties don’t depend upon the nature of particles “.

Why is carbon important for forming complicated molecules? Or why carbon makes a large number of molecules ?

The answer to this question is very simple . There are two major reasons behind it. 1. Catenation :- It is the property by which the carbon can make long chains, branched chains and ring or cylic structural by joining with its own atoms. Due to this it can make a variety of molecules. 2.
