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

1 answer


Nucleophilic reactions involve the attack of a nucleophile (electron-rich species) on an electrophile (electron-deficient species), resulting in the formation of a new chemical bond. This type of reaction often occurs in polar solvents and can lead to the formation of products with new functional groups. Common examples include nucleophilic substitution and nucleophilic addition reactions.

In organic chemistry reactions, nucleophilic addition to a carbonyl group occurs when a nucleophile attacks the electrophilic carbon atom of the carbonyl group, forming a new bond and resulting in the addition of the nucleophile to the carbonyl compound. This process typically involves the formation of a tetrahedral intermediate, which then collapses to yield the final product.

Carbonyl compounds are electrophilic due to the partially positive carbon atom. Nucleophiles are attracted to this electrophilic carbon atom, leading to a nucleophilic addition reaction. The nucleophile attacks the carbonyl carbon, forming a tetrahedral intermediate, which then collapses to form the final product.

In organic chemistry, the difference between 1,2 and 1,4 conjugate addition lies in the position of the double bond in the conjugated system. In 1,2 addition, the nucleophile adds to the carbon atoms directly next to the double bond, while in 1,4 addition, the nucleophile adds to the carbon atoms that are separated by two carbon atoms in the conjugated system.

The mechanism of the NACN acetone reaction involves the nucleophilic addition of cyanide ion to the carbonyl carbon of acetone, followed by proton transfer and elimination of cyanide ion to form a cyanohydrin product. This reaction helps in understanding the principles of nucleophilic addition reactions, carbonyl chemistry, and the importance of cyanide as a nucleophile in organic synthesis.

Formaldehye is H2C=O and has a double bond. The Carbon-oxygen bond is slightly polar and the carbon has partial positive charge and oxygen slightly negative charge. Hence formaldehyde will undergo nucleophilic addition addition reaction across the C=O.

A buffer solution is able to resist changes in pH upon addition of acid or base because it contains a weak acid and its conjugate base (or a weak base and its conjugate acid). When an acid is added, the conjugate base neutralizes it, and when a base is added, the weak acid neutralizes it, preventing significant changes in pH.

"Conjugate" usually means that in one of two parts, the sign is changed - as in a complex conjugate. If the second part is missing, the conjugate is the same as the original number - in this case, 100.

A nucleophile is a molecule or ion that donates an electron pair to form a new chemical bond with an electron-deficient atom, known as an electrophile. In organic chemistry, nucleophiles are important in reactions such as nucleophilic substitution and nucleophilic addition, where they attack and bond with electrophiles to form new compounds. This process is crucial for the synthesis of various organic molecules.

A buffer resists change in pH upon addition of a strong acid because it contains a weak acid and its conjugate base (or a weak base and its conjugate acid) which can neutralize the added acid by donating or accepting protons, thus maintaining the pH. The weak acid and its conjugate base components in the buffer solution help to absorb the added protons or hydroxide ions without significant change in pH.

No, Williamson's synthesis is an example of an SN2 (bimolecular nucleophilic substitution) reaction, not nucleophilic substitution. In this reaction, an alkyl halide reacts with a strong nucleophile to form an ether by substitution of the halogen atom.

Haloalkenes are more reactive towards nucleophilic substitution reactions because the presence of the electron-withdrawing halogen creates partial positive charge on the carbon, making it more prone to attack by nucleophiles. Additionally, the double bond in haloalkenes provides a site for nucleophilic attack, increasing the rate of reaction.

It depends on what the denominator was to start with: a surd or irrational or a complex number.

You need to find the conjugate and multiply the numerator by this conjugate as well as the denominator by the conjugate. Since multiplication is by [conjugate over conjugate], which equals 1, the value is not affected.

If a and b are rational numbers, then

conjugate of sqrt(b) = sqrt(b)

conjugate of a + sqrt(b) = a - sqrt(b), and

conjugate of a + ib = a - ib where i is the imaginary square root of -1.

Furan does not typically undergo nucleophilic substitution reactions because of its aromatic nature, which offers stability due to delocalization of the pi electrons in the ring. This makes furan less reactive towards nucleophilic attack compared to non-aromatic compounds.

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 ).
