Answer
When ethanoic acid (acetic acid) is mixed with sodium hydroxide (NaOH), a neutralization reaction occurs, resulting in the formation of sodium ethanoate (the sodium salt of ethanoic acid) and water. Since propanol does not react with NaOH, it will remain in the mixture, making this combination valid.
Step 2
B. Ethanoic acid and sodium propanoate

Answer
This mixture is not formed when NaOH is added, as sodium propanoate is not produced in this reaction.

Answer
Sodium hydroxide will react with ethanoic acid, not with propyl ethanoate, making this option incorrect.

Answer
Similar to option C, NaOH will not react with ethyl propanoate, so this option is also invalid.
