Yeah C is legitimately correct
The products are Ethanoic acid and propanol
CH3COOC3H7+H2O--->CH3COOH+C3H7OH
this is the acid hydrolysis
but if an alkaline is used in the hydrolysis the products would be The salt of the carboxylic acid and alkanol e.gThe hydrolysis CH3COOC3H7 in NaOH
CH3COOC3H7+NaOH-->CH3COONa+C3H7OH

Let's break down this chemistry problem step-by-step.
Understanding the Reaction
The reaction we're looking at is the acid hydrolysis of an ester. Esters are compounds with the general formula R-COOR', where R and R' are alkyl groups (chains of carbon and hydrogen).
In this specific case, the ester is:
CH3-C(=O)-OCH2CH2CH3
When an ester reacts with water in the presence of an acid (like HCl), it breaks apart (hydrolyzes) into two products:
* A carboxylic acid: This is formed from the part of the ester that has the carbonyl group (C=O). In this case, it will be CH3-COOH (acetic acid).
* An alcohol: This is formed from the other part of the ester (the -OR' group). In this case, it will be HOCH2CH2CH3 (propanol).
Analyzing the Options
Let's look at each option:
* A. CH3-C(=O)-OH + CH3CH2CH2Cl This is close! It has the correct carboxylic acid (CH3-COOH), but it shows the alcohol as a chloride (CH3CH2CH2Cl). This is incorrect because the reaction is with water, not HCl.
* B. CH3CH2CH2OH + CH3-C(=O)-Cl This has the correct alcohol (CH3CH2CH2OH), but it shows the carboxylic acid as an acid chloride (CH3-C(=O)-Cl). Acid chlorides are not formed in acid hydrolysis of esters.
* C. CH3-C(=O)-OH + HOCH2CH2CH3 This is correct! It shows the correct carboxylic acid (CH3-COOH) and the correct alcohol (HOCH2CH2CH3).
* D. CH3-C(=O)-OH + CH3CH3 This has the correct carboxylic acid, but the second product (CH3CH3, ethane) is not formed in this reaction.
* E. CH3CH2C(=O)-OH + CH3CH2OH This has the wrong carboxylic acid (it's missing a carbon) and the wrong alcohol (it's ethanol, not propanol).
The Answer
The correct answer is C. The products formed from the acid hydrolysis of CH3-C(=O)-OCH2CH2CH3 are CH3-COOH (acetic acid) and HOCH2CH2CH3 (propanol).

Those going with C
there's an extra Oxygen molecule
where did it come from?
