When alcohols act as nucleophile. ? give example?

Question

Answer

Yes alcohol is versatile compound so it acts both nucleophile and electrophile..in nucleophile O-H bond is broken down(eg: R-O-H +C gives rise to R-O-C + H^+)in electrophile C-O bond is broken down(eg: Br-R-CH2-OH2 gives rise to Br-R-CH2 + H2O)...hope u understand..

Answer

Yes alcohol is a versatile compound so it acts as both nucleophile and electrophile..and i gI've both answer in this question itself...in nucleophile bond between O-H will broken (eg: R-O-H + C gives R-O-C + H^+)and in electrophiles the bond between C-O is broken mostly protonated alcohol react by this manner (eg:Br-CH2-R-OH gives rise to Br-CH2-R + H2O)...hope u understand

Answer

Alcohols as Nucleophiles

When alcohols act as nucleophiles, they donate a pair of electrons to another molecule in a chemical reaction. This occurs when the hydroxyl group (-OH) of the alcohol attacks an electrophilic center, leading to the formation of a new bond.

Example:
One common example is the nucleophilic substitution reaction of an alcohol with an alkyl halide to form an ether. In this reaction, the lone pair of electrons on the oxygen atom of the alcohol attacks the electrophilic carbon of the alkyl halide, resulting in the formation of the ether and a halide ion as a leaving group.

Explanation:
- The alcohol molecule acts as a nucleophile by donating its lone pair of electrons to the carbon atom of the alkyl halide.
- This results in the formation of a new bond between the oxygen atom of the alcohol and the carbon atom of the alkyl halide, leading to the formation of an ether.
- The leaving group (halide ion) is expelled from the alkyl halide molecule.
- The overall reaction involves the substitution of the halide ion with the alkyl group from the alcohol, resulting in the formation of the ether product.

In conclusion, alcohols can act as nucleophiles in various organic reactions, such as nucleophilic substitution reactions. Understanding the reactivity of alcohols as nucleophiles is important in organic chemistry for predicting and controlling the outcome of chemical reactions.
