Luca's test is used to determine the type of. Rectified spirit is 100% ethanol. Which of the following compounds will give a positive iodoform test? The characteristic reaction of carboxylic acids is.
Understand the Problem
The question is asking about multiple choice questions related to Pharmaceutical Organic Chemistry, specifically focusing on tests and reactions pertinent to organic compounds.
Answer
1. Alcohols 2. 95% ethanol 3. 3-pentanone 4. Nucleophilic addition
- Lucas test is used to determine the type of alcohols. 2. Rectified spirit is 95% ethanol. 3. 3-pentanone will give a positive iodoform test. 4. The characteristic reaction of carboxylic acids is nucleophilic addition.
Answer for screen readers
- Lucas test is used to determine the type of alcohols. 2. Rectified spirit is 95% ethanol. 3. 3-pentanone will give a positive iodoform test. 4. The characteristic reaction of carboxylic acids is nucleophilic addition.
More Information
Lucas test is used for distinguishing alcohols; rectified spirit is usually not 100% ethanol; and carboxylic acids undergo nucleophilic addition as a characteristic reaction.
Tips
A common mistake is confusing Lucas test for aldehydes or detecting over 95% ethanol in rectified spirits.
