Which of the following compounds will react with sodium hydroxide solu...
Explanation:
Reactivity with Sodium Hydroxide Solution:
- When a compound reacts with sodium hydroxide solution in water, it undergoes a reaction known as alkaline hydrolysis.
- Alkaline hydrolysis involves the breaking of chemical bonds in the compound due to the presence of hydroxide ions (OH-) from the sodium hydroxide solution.
Analysis of Compounds:
- C6H5OH (Phenol): Phenol is a compound with a hydroxyl group (-OH) attached to a benzene ring. This hydroxyl group can react with sodium hydroxide solution through alkaline hydrolysis.
- C6H5CH2OH (Benzyl alcohol): Benzyl alcohol also contains a hydroxyl group (-OH), which can react with sodium hydroxide solution.
- (CH3)3COH (Tertiary butanol): Tertiary butanol is a tertiary alcohol, which does not undergo alkaline hydrolysis due to the absence of a reactive hydrogen atom.
- C2H5OH (Ethanol): Ethanol is a primary alcohol and can react with sodium hydroxide solution through alkaline hydrolysis.
Conclusion:
- Among the given options, only C6H5OH (Phenol) and C2H5OH (Ethanol) will react with sodium hydroxide solution in water due to the presence of hydroxyl groups that can undergo alkaline hydrolysis.
