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 ?”

How the addition of hydrogen halide takes place in case of unsymmetrical alkenes ?

In case of unsymmetrical alkenes the addition of hydrogen halide takes place according to the markovnikov’s rule . During this reaction under markovnikov’s rule the positive part of the attacking reagent joins with the carbon with more number of Hydrogen and the negative part of attacking reagent joins with the more substituted carbon.

How we can prepare dibromoethane from ethene ?

We can make the dibromoethane from ethene by the addition of halogen in ethene , in the presence of carbon tetrachloride. In the presence of ether as a solvent the above reaction takes place. The dihalo products are formed in which the halogen groups are present on adjacent carbon atoms.

Mechanism for electrophillic addition reactions of alkenes

The mechanism involves the following steps :- Step 1 :- In first step the polarity is developed on the bromine molecule , and the partial positive side of the bromine molecule attacks on the carbon atom of the double bond. This leads to the formation of carbocation. Step 2 :- In second step the negativeContinue reading “Mechanism for electrophillic addition reactions of alkenes”

Why the alkenes give electrophillic addition reactions ?

Alkenes give electrophillic addition reactions because of the following reasons:- 1. The pie electrons of the double bond attract electrophiles . 2. The electron density is more on the C-C double bond , so the electrophiles preferably attack on it as compared to the electrophiles which are repelled.
