Chemical kinetics । रासायनिक बलगतिकी। Class 12 । Neet & Jee
In video we discussed about the molecular collision theory. The molecules of reactant continuously collide to each other. As a result of their collision product is formed. In every collision product do not form. In few fraction of collision product form.
The collision in which product form is known as effective collision the collision in which product do not form know as ineffective collision.
Any collision to be effective the molecules of reactants must overcome two barrier.
1. Orientation barrier and
2. Energy barrier.
The molecules of reactants must collide in a proper orientation to form intermediate which is also known as coordinate complex.
The molecules of reactants must have a minimum ...

In video we discussed about the factors affecting the rate of reactions. The following factors affect the rate of reaction 1. Temperature 2. Concentration 3. Catalyst The effect of temperature is given by arrhenius equation. By increasing temperature the rate of reactions also increase due to increase in rate constant and increase in effective nuclear charge .

In video we discussed about the order of reaction. Order of reaction is defined as the sum of power raised to the concentration of reactant in rate law equation. Order of reactions can be determined in laboratory. Sum of power raised to the concentration may or may not be equal to the order of reactions. Zero order reaction is defined as the rate of reaction is directly proportional to the conc...

In video we discussed about the instantaneous rate of reactions. Instantaneous rate of reaction is defined as the small change of concentration in small time at any given time. Rate of reactions is directly proportional to the concentration of reactant raised appropriate power is known as rate law. Sum of power of reactants in rate law equation is known as order of reactions. Order of reaction ...

In video we discussed about the chemical kinetics. Chemical kinetics is the branch of science which deals with the rate of reactions and factors affecting rate of reactions. Rate of reactions is defined as the change in concentration of reactant or product with respect to time. Rate of reactions have significant value in our daily life and commercial activities.

In video we discussed about the method of preparation of carboxylic acid. Carboxylic acid is prepared by the nitiles on hydration. Carboxylic acid also prepared by reaction of Grignard reagent with carbon dioxide followed by hydrolysis. Reaction of Grignard reagent is a kind of carboxylation reaction. Carboxylation reaction is a kind of reaction in which product have greater number of carbon at...

In video we discussed about the reaction of aldehyde and ketone with hypohalites. Reaction with hypohalites is a kind of oxidation reaction. The aldehyde and ketone and alcohol in which atleast one methyl group attached with either carbonyl carbon or functional group carbon undergo reaction with hypohalites. Such aldehyde and ketone and alcohol oxidises into Carboxylic acid and form haloform. I...

In video we discussed about the cross aldol Condensation reaction. Aldehyde and ketone which have alpha hydrogen undergoes aldol Condensation reaction. Cross aldol Condensation reaction takes place when two different aldehyde and ketone undergoes cross aldol reaction. There four or less than kind of product will form depending upon the nature and structure of aldehyde and ketone undergoes aldol...

In video we discussed about the reduction of aldehyde and ketone . Aldehyde and ketone are reduced by lo lithium aluminium hydride and sodium boro hydride into primary and secondary alcohol respectively. Sodium boro hydride is a selective reducing agent which reduces only aldehyde and ketone and not ester , carboxylic acid and amide. The aldehyde and ketone which have alpha hydrogen with itself...
GOC - Optical Isomerism । Class-11 । Neet and jee
Просмотров 1125 дней назад
In video we discussed about optical isomerism. Enantiomers are the compounds which are mirror images of each other and non superimposable. Enantiomers have similar physical properties except rotation of plane polarized light. Enantiomers have same chemical properties. Diastereomers are neither mirror images of each other nor superimpolable. Diastereomers have different physical properties and s...

I love your lectures sir because you don't waste your time in meaningless discussions like other teachers but straight to the point .
thank you sir , kal mera test hai aapne sab bhuladia.😢😢 edit: bhuladia nahi yaad kara dia edit 2: galti se hogya wo edit 3: mujhe lgta edit 2 unnessery . edit4: unnecessary ka speeling correct karunga edit5 *spelling
Super classs
