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.

It is a two step reaction in which 1. di-alkyl benzene is oxidised 2. In step two , the acidic environment helps in providing the Hydronium ions and they easily get converted into a carboxylic acid .
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 charge
These are the cells in which non reversible redox reaction takes place. That is they can give electrical energy only once at the cost of reaction taking place in them , once the reaction is over , the cells get exhausted and can not be used again. And these cells can never be recharged agin.
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 it
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
NH3 gives deep blue colored mine complex compound on reacting with Cu²+.
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.
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
To answer this we have to see the reactive nature of phenol and the substituents attached to it. Acidic behavior of phenol depends on the fact that how easily it can loose a proton and make phenoxide ion which is stabilized by resonance. The methoxy group being electron donating group increases the electron density of
The structure of XeOF4 is square pyramidal. And its hybridization is sp³d² The structure of XeO3 is pyramidal and its hybridization is sp³.
Chlorobenzene and bromobenzene can be prepared by treating bezenediazonium chloride with cuprous chloride or cuprous bromide. This reaction is also called Sandmeyer’s reaction.
Actually the sigma bond involves head to head overlapping of orbitals, due to which the overlapping takes place on a larger extent. That makes the bond more stronger as compared to pie bond. In pie bond there is a sidewise overlapping of orbitals which leads to lesser extent of overlapping and thus the bond formed
It states that for a solution of volatile components, the partial vapour pressure of each component is directly proportion to the mole fraction of the component in the solution.
1.Temperature :- With increase in temperature the rate of vaporization also increase thus it creates more pressure. Moreover with increase in temperature the kinetic energy of the vapours also increase. 2. Nature of liquid:- The liquids with lower inter-particulate attractions have high vapour pressure as the formation of vapours is easy . Like acetone is
Calculate the radius of copper atom if it crystallise in face centred cubic lattice and has a density of 8.93 g / cm cube. Solution Structure given = fcc For fcc , Z = 4 Density , d = 8.93 Molar mass , M = 63.55 Avogadro number = 6.2×10^23 Use the given formula In
The elements belonging to Group 1 and group 2 of periodic table has the strong tendency to form cations. The reason behind this tendency is that the elements belonging to group 1 and 2 have one and two valance electrons respectively. By loosing the valence electrons, they will aquire noble gas configuration. It is easy
perkin reaction
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 ion
Chemical bond may be defined as the force of attraction by which two atoms are held together. The chemical bonds lead to the formation of molecules and crystals. There are various kind of bonding that we see around us. Covalent bond A covalent bond is formed by mutual sharing of electrons between two atoms. For
Stereoisomers:- these are the compounds that have same molecular formula but different arrangement of atoms in the space. Optical isomers:- the compunds that have same molecular formula but they rotate the plane polarised light to the different side, right side-dextrorotatory and left levorotatory. Enantiomer:- these are the compounds that are mirror images of each other
