What is product of cyclohexene react with bromine?
When cyclohexene(C6H10) reacts with bromine (Br2), trans-1,2-cyclohexane.This stereochemistry is obtained because bromine acts as both an electrophile and a nucleophile creating a cyclic bromonium ion intermediate. This means the second bromine, which acts as a nucleophile, can only attack the partially positive carbon from the opposite side of the side that is a part of the cyclic bromonium ring.
Is sodium Cynide a base?
Sodium cyanide is the salt of weak acid and strong base and when it is dissolved in water it gives the basic media. The ions Na+ and CN- second is the strong nucleophile. While first is the weak electrophile. Same is the case of sodium methoxide.
Is NO2 a electrophile?
NO2+ is.
What would be the effect of carrying out the sodium iodide in acetone reaction with the alkyhalides using an iodide solution half as concentrated?
A reaction with alkyl halides in NaI with acetone is by the Sn2 mechanism. The rate for an Sn2 mechanism is directly proportional to the concentration of the nucleophile: rate = k[nucleophile][alkylhalide] If the iodine solution (the nucleophile) is half as concentrated, then the rate will also be halved. rate = k [nucleophile]/2 [alkyl halide]
Is triethylamine a better nucleophile than ethanol?
No, Nucleophilicity is not the same thing as basiscity. Although Triethylamine is a strongerbase it is a far worse nucleophile. Nucleophilicity is dependent on sterics and whethe the incoming nuclophile can form a stable complex. In the case of triethylamine any complex formed will have a fomal positive charge on the Nitrogen and because all of its substituents are alkyl groups it can not loose them to become neutral. Ethanol on the other hand can loose a proton to form an ethoxide linkage and is the bette nucleophile but weaker base
What's the difference in indicator and reagent?
Indicator will changes the colour according to H+ ion present in a solution. Reagent : consist of electrophile and nucleophile. It help in the attachment of nucleophile to the electrophile and electrophile to the nucleophile. Mirza
Why hydrogen bromide is electrophile?
hydrogen bromide is not the electrophile its bromide ion may act as the nucleophile, in alkyl halide the alkyl group may act as an electrophile.
Which is both nucleophile and electrophile among ch3cn ch2oh ch2chch3 ch3nh2?
Ch3CN
Why halogens act both as an electrophile and nucleophile?
depending upon the reaction conditions halogens act as electrophiles,nucleophiles and freeradicals
What is electrophillic?
An electrophile is any an agent that is attracted to electrons. The electrophiles stimulate a chemical reaction by bonding with a nucleophile, creating an electron pair.
Is fluorine more reactive than acylchloride?
No, acyl chloride is very reactive as both an electrophile or a nucleophile. Fluorine is just very electronegative.

Why do we call a nucleophilic addition as 1 2 nucleophilic addition or 1 4 nucleophilic addition?
1,2-addition occurs when the carbonyl oxygen (1) is attached by the electrophile and the carbonyl carbon (2) attaches to the nucleophile for the 1,4 the 4 is the beta carbon

Is NO2 a electrophile?
NO2+ is.
What are electrophiles and nucleophiles?
Electrophiles and Nucleophiles are atoms, bonds, or (small or small parts of) compounds that are involved in chemical reactions.Nucleophiles are "nucleus loving" which means that they want to give up electrons and gain a bond with another atom. These are usually negative or neutral compounds. (-OH base is a good example, the oxygen usually gives electrons)Electrophiles are the opposite, they are "electron loving" which means that they gain electrons (from the nucleophile to form a new bond). (A carbon-carbon double bond or hydrogen molecule can act as an electrophile for example.)
In Reimer Tiemann reaction of phenol with CCl4 to from the trichloromethane derivative what is the electrophile or the mechanism?
In Reimer- Tieman reaction the electrophile is dichlorocarbene
