Ethanoyl chloride on hydrolysis with aqueous NaOH gives _______a)aceta...
Explanation:
When ethanoyl chloride (also known as acetyl chloride) reacts with aqueous sodium hydroxide (NaOH), it undergoes hydrolysis to form acetate ions (CH3COO-) and water (H2O).
Hydrolysis reaction:
CH3COCl + NaOH → CH3COO- + Na+ + H2O
Explanation:
- Ethanoyl chloride (CH3COCl) is a derivative of acetic acid (CH3COOH), where one of the hydrogens in the carboxylic acid group has been replaced by a chlorine atom.
- Aqueous sodium hydroxide (NaOH) is a strong base that can react with ethanoyl chloride.
- In the hydrolysis reaction, the chlorine atom in ethanoyl chloride is replaced by a hydroxyl group (OH-) from sodium hydroxide.
- The resulting product is acetate ion (CH3COO-), which is the conjugate base of acetic acid.
- Sodium ion (Na+) is also formed as a spectator ion.
- Water (H2O) is produced as a byproduct of the reaction.
Result:
The hydrolysis of ethanoyl chloride with aqueous NaOH gives acetate ions (CH3COO-).
Note: Acetate ions can further react with water to form acetic acid, but this reaction is not specified in the given options.
