Why Formaldehyde is more reactive then other aldehydes? justify .

The reactivity of Aldehydes depend upon two factors . 1 Steric effect :- The reactivity of aldehyde depends upon the fact that the nucleophile will attack on the Carbon atom of the carbonyl group. If it is less crowded the nucleophile can easily approach it and can easily react. So lesser is the hinderance moreContinue reading “Why Formaldehyde is more reactive then other aldehydes? justify .”

why do aldehydes and ketones undergo nucleophillic addition reaction ?

in case of aldehydes and ketones there is a carbonyl group present in the molecule as shown below :- The oxygen is more electrongative than the carbon , due this the polarity develops in the C=O bond. The carbon becomes partially positive and the oxygen becomes partially negative . This decreases the electron density onContinue reading “why do aldehydes and ketones undergo nucleophillic addition reaction ?”

The rate constant of a first order reaction is 3.0 x 10 -8 s-1 . what is the rate of the reaction when the concentration of reactant is 1.5 mol L-1 ?

The rate constant of a first order reaction is 3.0 x 10 -8 s-1 . what is the rate of the reaction when the concentration of reactant is 1.5 mol L-1

For the reaction : N2  +  3H2  → 2NH3  , the rate of reaction measured as ∆[NH3]/∆t was found to be 2.4 x 10-4 mol L-1 s -1 . Calculate the rate of reaction expressed in terms of (i) N2 and (ii) H2 .

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 mechanism for anti markovnikov addition or kharasch effect or peroxide effect ?

The mechanism for this kind of reaction involves the formation of free radicals, and the relative stability of different molecules will decide the formation of major and minor products. Step 1 , Chain initiation :- First of all , the homolytic cleavage takes place in peroxide molecule as shown below :- Step2 Chain propagation :-Continue reading “What is the mechanism for anti markovnikov addition or kharasch effect or peroxide effect ?”

What is anti markovnikov addition or peroxide effect or Kharasch effect ?

It is the phenomenon which is seen in case of addition of hydrogen halide in the presence of a peroxide like benzoyl peroxide. The major product in this kind of reaction is the alkane in which the halide is attached to terminal or the less substituted carbon atom as shown below.

Why the but-2-ene is major product of beta elimination of 2-Bromobutane ?

This is due to the following reason :- This is in accordance with sytzeff rule that whenever two alkenes are theoretically possible during a dehydrohalogenation reaction , it is always the more highly substituted alkene which predominates . It can also be best understood by the following illustrations showing the stabilizes of primary(1°) , secondaryContinue reading “Why the but-2-ene is major product of beta elimination of 2-Bromobutane ?”
