You are thinking of condensation in daily life, like when steam cools and becomes water droplets on a cold surface. That idea is correct, but that is physical chemistry, not organic chemistry.
So let’s separate it clearly in your mind.
In everyday life, condensation means gas turning into liquid. Like steam from hot water hitting a cold mirror and forming droplets. That is a change of state. No new substance is formed, it is still water, just in a different form.
But in Chemistry, especially organic chemistry, the word “condensation reaction” is used differently. It does NOT mean boiling or cooling. It means:
👉 two molecules join together
👉 and a small molecule like water is removed
👉 a new, bigger molecule is formed
So it is not about temperature change. It is about molecules combining.
Now let’s connect this back to esterification.
Esterification is: acid + alcohol → ester + water
What is happening there? Two molecules are joining, and water is removed. That is exactly the Chemistry definition of condensation reaction.
So here is the key truth you need to lock in:
There are two meanings of condensation, depending on context.
One is the everyday meaning you already know, which is steam becoming water.
The other is the Chemistry meaning, which is joining molecules with loss of water.
JAMB is using the Chemistry meaning.
So when you saw “condensation”, your brain went to boiling and steam, but the exam is talking about molecular reactions, not physical changes of state.
That is why option C is correct.
If I reduce it to one very simple sentence you can carry into the exam hall, it is this:
👉 In organic Chemistry, condensation means joining two molecules while water is produced.
Esterification fits that perfectly.
The correct option is B please.
An esterification reaction is similar to a neutralisation reaction in the sense that two different compounds react by one donating a proton and the other donating an electron pair.
The question is saying: esterification is analogous to what?
Now that word “analogous” is just a fancy way of saying “similar to” or “works in a similar way as”. So they are not asking you to define esterification again. They are asking you to match it with another type of reaction that behaves in the same pattern.
So the real work here is not the options. The real work is: what exactly is esterification?
Let’s build it from scratch.
Esterification is a reaction between an acid and an alcohol to form an ester and water. In simple words, two different substances join together and in the process, a small molecule, usually water, is eliminated. So it is a combination process where something is formed and water comes out as a byproduct.
Now keep that idea in your head: joining together and losing water.
Let’s now carefully go through the options one by one and see which one behaves in a similar way.
Option A talks about oxidation reactions. Oxidation is about adding oxygen or removing hydrogen. It has nothing to do with combining two molecules to form a bigger one with water being removed. So it does not match the pattern of esterification.
Option B talks about neutralization reactions. Neutralization is acid plus base forming salt and water. At first glance, you might feel it looks similar because water is produced. But the actual process is different. Neutralization is not forming a large organic molecule by combining two substances in a dehydration process. It is simply acid-base reaction producing salt and water. So while water appears, the mechanism and idea behind it is not the same as esterification in organic chemistry sense.
Option C talks about condensation reactions. This is where things start to line up properly. A condensation reaction is one where two molecules join together and a small molecule, usually water, is eliminated. That description is almost a direct mirror of esterification. In esterification, an acid and an alcohol combine and water is removed. That is exactly what condensation reactions are defined by.
Now option D is hydrolysis. Hydrolysis is basically the opposite of esterification. Instead of joining molecules together, it breaks them apart using water. So instead of forming an ester and producing water, it uses water to break the ester down. So it is literally the reverse process, not the same one.
So when you compare everything carefully, only one option matches the idea of “joining molecules with removal of water”, and that is condensation.
So the correct answer is C.
Now let me help you lock this in your mind in a way that will stop confusion in the exam hall. Esterification is basically a type of condensation reaction in organic chemistry. That is the relationship JAMB wants you to remember. Acid plus alcohol joins together, water leaves, ester is formed. That is condensation in action.
What usually confuses students is option B because neutralization also produces water, so it feels similar. But the difference is what is actually being formed. Neutralization forms salt, esterification forms an ester. One is inorganic acid-base chemistry, the other is organic molecule building. That is the separation point.
So if you ever see esterification again, your brain should immediately think: “this is condensation involving organic compounds”.
The answer is condensation because both involve a both involve the elimination of a small molecule which is water
the answer is wrong, Esterification reaction is analogous to Neutralization reason being that, Neutralization reaction invlove a mineral acid reacting with a mineral base, while Esterification reaction involves an organic acid reacting with an Organic base
Greetings, The Myschool Team.
The correct answer is B(neutralization reaction) and not C(condensation reaction). Condensation would not be correct as two products(ester and water) are formed. However, neutralization is appropriate, as it involves the reaction between an acid(alkanoic acid in this case) and base(alkanol) to form a salt(ester) and water. Thus, the correct answer is B(neutralization reaction) and not C (condensation reaction). Thank you.
