1.	Can we use nucelophiles such as NH3 ,CH3O for the Nucleophilic substitution of alcohols
Answer» 1. Increasing order of nucelophilicity, NH₃ < – OH^⊕ < CH₃O^⊖- 2. Higher electron density will increase the nucelophilicity. 3. Negatively charged species are almost always more nucelophiles than neutral species. 4. RO^⊖ has an alkyl group attached, allowing a greater amount of polarizability. This means oxygen’s lone pairs will be more readily available to reach in RO^⊖ than in OH^⊖ . Hence CH₃O – is the better nucelophile for the nucleophilic substitution of alcohols. NH₃ cannot act as nucelophile for the nucleophilic substitution of alcohols.

Can we use nucelophiles such as NH3 ,CH3O for the Nucleophilic substitution of alcohols

Answer»

1. Increasing order of nucelophilicity,

NH₃ < – OH^⊕ < CH₃O^⊖-

2. Higher electron density will increase the nucelophilicity.

3. Negatively charged species are almost always more nucelophiles than neutral species.

4. RO^⊖ has an alkyl group attached, allowing a greater amount of polarizability. This means oxygen’s lone pairs will be more readily available to reach in RO^⊖ than in OH^⊖ .

Hence CH₃O – is the better nucelophile for the nucleophilic substitution of alcohols. NH₃ cannot act as nucelophile for the nucleophilic substitution of alcohols.
