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.

Out of alkenes (ethylene) and alkynes (acetylene) which is more acidic and why ?
The alkynes are more acidic in nature as compared to the alkenes . This is due to the fact that the alkynes give hydrogen on reacting with sodium metal, but Alkenes don’t give hydrogen. The alkynes release hydrogen and forms a sodium salt which clearly shows it’s acidic nature.
How we can prepare Propanoic acid from butane-2-one and Butan-2-ol ?
In this method the methyl ketone is treated firstly with sodium hydroxide so we get the sodium salt of acid which is further treated with hydrochloric acid to get the final product , that is a carboxylic acid.
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 byContinue reading “how we can prepare carboxylic acid (benzoic acid) from acyl halides and acid anhydrides (benzoic anhydride)”
Why Carboxylic Acids are more acidic than phenols ?
In case of carboxylic acids the negative charge is on the more electronegative element that is oxygen as shown in the structure in both of the resonating structures. The negative charge on the more electronegative element makes it more stable. And thus it shows acidic character easily. But in case of phenols the negative chargeContinue reading “Why Carboxylic Acids are more acidic than phenols ?”
This mechanism is seen in Nucleophillic Substitution reactions, especially in those compounds in which the Carbon atom is more substituted . The rate of this mechanism depends on the step 1 where the leaving group leave with electron pair and leaves behind a carbocation. The whole rate depends only on one molecule. That’s why itContinue reading “SN1 mechanism”
It is the reaction that leads to the production of aromatic aldehydes mostly the ortho substituted ones. It is a reaction that yields orthohydroxy (major product) and para hydroxy (minor product). It basically a reaction between phenol and chloroform in the presence of aqueous sodium hydroxide. contribute to help us serve you better.
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 toContinue reading “Stobbe reaction and its Mechanism”
Preparation of chlorobenzene – Sandmeyer’s reaction
Chlorobenzene and bromobenzene can be prepared by treating bezenediazonium chloride with cuprous chloride or cuprous bromide. This reaction is also called Sandmeyer’s reaction. The reaction is named after the Swiss Chemist Traugott Sandmeyer. In this reaction the diazonium group losses the molecule of dinitrogen and it yields chlorobenzene.
What are the chemical properties of Carboxylic Acids ?
Why is breaking of C-H bond given more preference over C-C bond though the bond energy of the latter is less than the first one?
In case of hydrocarbons , the c-c bond is normally safe due to following two reasons :- Difference between the electronegativity of Carbon and Hydrogen. Due to this reason the electrons of the shared pair stays closer to the C-atom which makes it easy to break the C-H bond and release hydrogen as hydronium ionContinue reading “Why is breaking of C-H bond given more preference over C-C bond though the bond energy of the latter is less than the first one?”
