ARgh....damn me for leaving this assignment till the last possible minute.

Q: What is the state of sulfur dioxide at room temperate? Why?

Thank you lifesavers!

thats your assignment? how long of a answer do you need?

a short answer would be: sulfur dioxide is a colorless gas with a suffocating, choking odor. since it has boiling point -10 C, at room temperature (which is 25 C) it is a gas.

Info on sulfur dioxide can be found in your SI Chemical data book, or a quick google search will do it...

If you need more info, see here

From the wording, seems like the same place abdoooo got the info from .

actually i remembered that from one of the notes that i got... which is exactly the same as that site .

I dont have a data book. The marks alloted to it were 3marks... It was only one part of the assignment. There were other uestions (excuse the lack of the letter cue my keyboard broke) and essays.

if its a three mark question, you should probably write more. write something about SO2's intermolecular forces. say that it does not have H-bonding and say that it contains despersion and is slightly polar. because of SO2 molecular geometry is bent and S is more electropositive than O resulting in dipole to dipole force. then relate this to its low boiling of -10 C.

LOL well your teacher's favourite site then

Do you mean dispersion forces? Everything has those, it's worth mentioning but not an explanation for this specific case . Good answer, but I would rephrase it, saying that O is more electronegative than S (it's the canonical form ), therefore slight dipoles form, therefore the molecule is polar...

This site gives a great explanation, including the resonance structures may get you Brownie points because most people haven't heard of them .

yeah i meant to say dispersion forces, i always miss a word or two in exams and then lose marks for it .

but electropostive sounds better...
