Why does nitrate ion is a weak nucleophile in sn1 reaction?
In a SN1 reaction, the nucleophile (in this case, nitrate ion) attacks the carbon atom that is bonded to the leaving group. Since the carbon atom is already bonded to the leaving group, it is not as electronegative as it would be if it were bonded to a hydrogen atom. This makes the carbon atom a less effective nucleophile. In addition, the nitrate ion is a weaker nucleophile than other nucleophiles, such as halide ions, because it is not as electronegative.
Why alkenes undergo nucleophilic addition reaction while simple alkanes do not?
Alkenes have pi bonds that are readily available to react because the strength of a pi bond isn't as strong as a sigma bond. Pi electrons will attack the nucleophile to form the respective carbocation. Alkanes only contain sigma bonds and have no pi electrons to attack a nucleophile. In order for an alkane to become a strong enough nucleophile it must not be sterically hindered (primary carbons prefered to tertiary) and most likely deprotenated by a very strong base ( likely stronger than sodium amide ).
Nucleophiles in a williamson ether synthesis of propyl p-Tolyl Ether?
The phonoxide anion is the nucleophile. CH3--(benzene ring)--O- AKA ArO-
Why Alkyl Halides are good for attacked by nucleufile?
This is a really great question that I often drill into my students heads. During the attack of an alkyl halide by a nucleophile, we see the electrons from the Nucleophile emptying into the anti-bonding orbital present at the rear of the carbon atom. It is at this position..... backside.....that the large-lobed anti-bonding orbital is located. This is seen in the SN2 process. In an SN1 process, a carbocation can form,,,,, resulting in an sp2 intermediate....which can readily be attacked by a nucleophile. Halogens such as I- are excellent leaving groups since the anion is stable. F- is a poor leaving group, since the huge negative charge is so concentrated that is results in an unstablized anion.
Is CHOOH a weak acid or a weak base?
The formic acid is a weak acid.
Is H2O nucleophile or electrophile?
H20 is a nucleophile it has a free lone pair of electrons which is a main feature of nucleophile, however, it is a weak nucleophile

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
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.
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 nh3 a nucleophile?
Yes it is a nuclephile.It has a lone pair
Is NH3 electrophilic?
No it is not electrophilic.It is a nucleophile
Which is both nucleophile and electrophile among ch3cn ch2oh ch2chch3 ch3nh2?
Ch3CN
What difference between nucleophile and base?
Nu attacks carbon, Ba abstracts H2
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
Mechanism of nBuBr plus KCN------nBuCN?
The given reaction is:The given reaction is an SN2 reaction. In this reaction, CN−acts as the nucleophile and attacks the carbon atom to which Br is attached. CN−ion is an ambident nucleophile and can attack through both C and N. In this case, it attacks through the C-atom.
Why halogens act both as an electrophile and nucleophile?
depending upon the reaction conditions halogens act as electrophiles,nucleophiles and freeradicals
