The reaction between chloroethane CH3CH2Cl and aqueous sodium hydroxide NaOH is a nucleophilic substitution reaction, specifically an SN2 reaction. In this reaction, the hydroxide ion OH- acts as a nucleophile and attacks the electrophilic carbon atom in chloroethane, leading to the substitution of the chlorine atom with the hydroxide ion.Balanced equation:CH3CH2Cl + NaOH CH3CH2OH + NaClSteps involved:1. The hydroxide ion OH- acts as a nucleophile and attacks the electrophilic carbon atom in chloroethane, which is bonded to the chlorine atom.2. The carbon-chlorine bond starts to break as the carbon-oxygen bond begins to form. This occurs in a single concerted step, which is characteristic of an SN2 reaction.3. The chlorine atom leaves as a chloride ion Cl- , and the hydroxide ion has now replaced the chlorine atom, forming ethanol CH3CH2OH .Products formed:1. Ethanol CH3CH2OH 2. Sodium chloride NaCl
