Разве ты не чувствуешь запах дыма в коридоре?

Разве adds a nuance of surprise, doubt, or expectation that the answer should be yes.

So Разве ты не чувствуешь запах дыма в коридоре? is not just a neutral Don’t you smell smoke in the hallway? It feels more like:

• You mean you don’t smell smoke in the hallway?
• Can’t you smell smoke in the hallway?
• Surely you smell smoke in the hallway?

It often suggests the speaker thinks the smell should be obvious.

In Russian, as in English, a negative question can express expectation or surprise.

• Ты чувствуешь запах дыма? = Do you smell smoke?
• Разве ты не чувствуешь запах дыма? = Don’t you smell smoke? / Can’t you smell smoke?

The negative does not necessarily mean the speaker believes the answer is no. With разве, it often means the speaker expected yes.

Yes, ты could be omitted, because the verb ending -ешь already shows you singular:

• (Ты) не чувствуешь...

Russian often leaves out subject pronouns when they are clear from the verb.

But including ты can:

• make the sentence more direct,
• add emphasis,
• make the contrast clearer: You don’t smell it?

So here ты is natural and slightly more pointed than leaving it out.

Russian often uses чувствовать (to feel, sense) with запах (smell, odor) to express to smell something in the sense of perceiving an odor.

So:

• чувствовать запах = to smell / to sense a smell

This is very common and natural.

Russian also has пахнуть, but that works differently:

• Здесь пахнет дымом. = It smells like smoke here.
• Пальто пахнет дымом. = The coat smells of smoke.

So in your sentence, the focus is on you perceiving the smell, which is why чувствуешь запах works well.

Запах дыма literally means the smell of smoke.

Russian can sometimes express this idea in other ways, but чувствовать запах дыма is very straightforward and explicit: you are sensing the odor, not necessarily seeing the smoke itself.

Compare:

• чувствовать запах дыма = to smell the odor of smoke
• видеть дым = to see smoke

So this phrasing makes the meaning precise.

Because запах is followed by the genitive to show the smell of something.

So:

• запах кофе = the smell of coffee
• запах газа = the smell of gas
• запах дыма = the smell of smoke

This is a very common Russian pattern:

• noun + genitive = X of Y

Here:

• запах = nominative singular
• дыма = genitive singular of дым

Because after в when it means in or inside a location, Russian uses the prepositional case.

• в коридоре = in the hallway / in the corridor

Compare:

• в коридоре = location, in the hallway
• в коридор = motion into, into the hallway

So here the meaning is location, not movement, which is why коридоре is prepositional.

Yes. Russian word order is flexible, though different orders change emphasis.

The given sentence:

• Разве ты не чувствуешь запах дыма в коридоре?

is natural and neutral enough.

Other possible orders:

• Разве ты в коридоре не чувствуешь запах дыма?
  This may emphasize in the hallway.
• Разве запах дыма в коридоре ты не чувствуешь?
  This sounds more marked and emphatic.

Russian uses word order partly to manage focus and emphasis, not just grammar. The original order is probably the most ordinary choice.

Чувствовать is imperfective, and that fits because the sentence is about a current state or ongoing perception:

• Don’t you smell smoke?
• Aren’t you sensing this smell?

Imperfective is normal for general perception, ongoing experience, or repeated ability.

A perfective verb would not normally be used here in the same way. The speaker is not asking whether you completed an action; they are asking about your present sensory experience.

They are similar, but not identical.

Both can express surprise or disbelief, but разве often appears in questions that challenge an assumption and often expects the opposite of what is said.

• Разве ты не чувствуешь запах дыма? = Don’t you smell smoke? Surely you do?

Неужели often sounds more like genuine astonishment:

• Неужели ты не чувствуешь запах дыма? = You really don’t smell smoke?

So they overlap, but разве often feels a bit more argumentative or corrective, while неужели can sound more emotional or amazed.

Yes. Without разве, the sentence is still perfectly grammatical:

• Ты не чувствуешь запах дыма в коридоре?

That would usually sound less strongly surprised or less pointed. It can simply be a negative question: Don’t you smell smoke in the hallway?

Adding разве makes the speaker’s attitude clearer: they find it surprising that the other person might not notice it.

You would replace ты and the verb form with вы:

• Разве вы не чувствуете запах дыма в коридоре?

Changes:

• ты → вы
• чувствуешь → чувствуете

Everything else stays the same.

Usually yes, in this kind of sentence.

Коридор means corridor, hallway, or sometimes passage, depending on context. In a home, apartment building, office, or school, hallway is often the most natural English translation.

So в коридоре here is naturally in the hallway.

Yes, but the structure would be different.

For example:

• В коридоре пахнет дымом. = It smells like smoke in the hallway.

This version focuses on the smell being present in the hallway itself.

Your original sentence:

• Разве ты не чувствуешь запах дыма в коридоре?

focuses on your perception of that smell.

So both are natural, but they are built differently:

• пахнет дымом = it smells of smoke
• чувствовать запах дыма = to smell the odor of smoke

Запах is in the accusative singular, but because it is an inanimate masculine noun, its accusative form looks the same as the nominative:

• nominative: запах
• accusative: запах

It is accusative here because it is the direct object of чувствуешь:

• чувствуешь что? → запах

So the structure is:

• ты = subject
• не чувствуешь = verb
• запах = direct object
• дыма = genitive dependent on запах
• в коридоре = location
