Question 29
How many of the compounds shown will react with aqueous sodium hydroxide to form the sodium salt of a carboxylic acid? A 1 B 2 C 3 D 4
Worked Solution & Example Answer:How many of the compounds shown will react with aqueous sodium hydroxide to form the sodium salt of a carboxylic acid? A 1 B 2 C 3 D 4 - CIE - A-Level Chemistry - Question 29 - 2013 - Paper 1
Step 1
Identify the Compounds Capable of Forming Carboxylic Acids
Answer
To determine how many of the given compounds react with aqueous sodium hydroxide to form the sodium salt of a carboxylic acid, we need to identify the presence of a carboxylic acid functional group (-COOH) or a precursor that can be transformed into a carboxylic acid upon reaction.
Analyzing the structures of the provided compounds:
- Compound A: This does not contain a carboxylic acid functional group.
- Compound B: This compound contains the -COOH group and can react with sodium hydroxide.
- Compound C: Similar to compound B, this compound contains the -COOH group and will react with sodium hydroxide.
- Compound D: This compound also has a carboxylic acid group.
Thus, compounds B, C, and D will react with aqueous sodium hydroxide.
