Answer:
One nucleophilic center
Explanation;
Nucleophile:
Nucleophile is a substance which is nucleus loving in nature (Nucleo; Nucleus , phile; Loving). It is known as a specie which donates a lone pair of electrons to electrophile (electron loving) in a chemical reaction.
Thus, Nucleophile is the region of higher electron density in a molecule and attacks on the lower electron density region of another molecule. Also, the nucleophile can also contain a negative charge.
Number of Nucleophilic centers in Methanol:
The chemical structure of Methanol is attached below and it can be observed that the oxygen atom is containing two lone pair of electrons. Hence, the oxygen atom can act as a nucleophilic center. Therefore, there is only one nucleophilic center in methanol.
H₃C-OH + H₃C-Br → H₃C-O-CH₃ + HBr
In above reaction methanol is acting as a nucleophile and is attacking on electrophilic center (Carbon) of methyl bromide yielding dimethyl ether.
Answer:
There is one nucleophilic center present in methanol.
Further details:
Nucleophile:
Nucleophile is a chemical type that donates an electron pair to form a chemical bond in relation to a reaction. All molecules or ions with an allowed pair of electrons or at least one pi bond can turn as nucleophiles.
A molecule or ion that contributes a pair of electrons to form a new covalent bond is termed a nucleophile.
Methanol:
Methanol is a liquid chemical with the formula CH3OH (often abbreviated MeOH). It is neutral, unstable, flammable, and poisonous. Methanol is produced from the destructive distillation of wood and is primarily manufactured from carbon monoxide and hydrogen. Its major uses are in organic separation, as a fuel, flush, and antifreeze.
Nucleophilic center in methanol:
If we see the chemical structure of methanol than it can be observed that the oxygen atom is containing two lone pair of electrons. So, an atom of oxygen can turn as a nucleophilic center. Therefore, there is only one nucleophilic center in methanol.
H₃C-OH + H₃C-Br → H₃C-O-CH₃ + HBr
In following reaction methanol is performing as a nucleophile and is attacking on electrophilic center (Carbon) of methyl bromide yielding dimethyl ether.
