Give an example of a chemical reaction in chemical equilibrium. Define chemical equilibrium using your chemical equation.
Chemical equilibrium in which concentration of reactant and concentration of products is constant and it's do not change with respect to time.Example is that water flow from a tap

When a reaction gives both an SN1 product and an E1 product how to I distinguish which on is the major one? Similarly, how do I distinguish between SN2 and E2?
The SN2 an E2 reactions share a great number of similarities. Both require a good leaving group. SN2 reactions require a good nucleophile, while E2 reactions require a good base....

What is the difference between SN2 reaction and E2 reaction?
The SN2 reaction is a type of nucleophilic substitution, where a nucleophile attacks an electrophilic center and bonds to it, expelling another group called a leaving group. Thus the incoming...

What is the best way to prepare CH3OCH(CH3)2 by an SN2 reaction?
(1) (CH3)2CHI and CH3ONa
(2) CH3OH and (CH3)2CHI
(3) CH3Br and (CH3)2CHOH
(4) CH3I and NaOCH(CH3)2
Answer: (4) CH3I and NaOCH(CH3)2

In SN2 mechanism inversion of configuration takes place. Explain.
Since in case of SN2 mechanism the nucleophile attacks from backside and the leaving group leaves from he front side the configuration is reversed.Backside attack is preffered as compared to...

Which one of the following would undergo faster SN2 reaction? Explain
CH3 – CH = CH – Cl or CH3CH2CH2 – Cl
In vinyl chloride (CH3-CH=CH-Cl) lone pair of chlorine is in resonance so chlorine will not get removed easily while in case of alkyl chloride resonance is not present.There's no such...

Primary alkyl halids show E-2 and SN2 reactions not E-1 and SN1 reaction. Why?
The “big barrier” to the SN2 reaction is steric hindrance. The rate of SN2 reactions goes primary > secondary > tertiary. The “big barrier” to the SN1 and E1 reactions is carbocation stability. The E2 reaction has no “big barrier”,...

what is [SN2]A and [SN2]AE mechanism?
[SN2]AE is nucleophillic addition-elimination, occurs whenever you havecarbonyl compound with a good leaving group attached at the alpha position to the carbonyl carbon. [SN2]A is something weird, maybe it is...

Which one of the following would undergo faster SN2 reaction? Explain CH3-CH=Cl or CH3-CH2-CH2-Cl
Answer: SN2 reaction happen faster in SP3 carbon center compair to SP2 carbon center. In given molecule CH3-CH2-CH2-Cl has SP3 center but CH3-CH=Cl has SP2 center.CH3-CH2-CH2-Cl undergoesfaster SN2 reaction than...

Which one of the following would undergo faster SN2 reaction? Explain
CH3 – CH = CH – Cl
or
CH3CH2CH2 – Cl
Solution.Chlorpropane will undergo a faster SN2 reaction than chlorpropenyl, because SN2 reactions occur most quickly for primary alkanes. Vinyl alkyl halides practically do not enter into this mechanism due to...
