Although LPG is a odourless gas , why can we smell it when it leaks?
If possible,give the name of the smelling compound that is mixed with LPG?

Have you made the slightest effort to look this up? I think you may have misunderstood the point of PF. We are not one of those Q&A sites where you just ask a question and get an answer. Here you are expect to make some effort on your own, and I found this question to be trivially easy to get an answer to.

No, I will no apologize. I stated a fact. If you don't like the fact, or if you don't like my post, there is a "report" button which you can use to complain to a moderator about my behavior. Did you read the link I provided? It explains why I posted what I did.
 
I read that link.I am very a shameful for what I did.
Please beg me pardon.

It's not a problem, I just wanted to make sure you understand what forum you have joined. This is a FANTASTICALLY good forum, it's just not one of those Q&A forums. People here don't give answers so much as try to help people figure out how to get answers on their own. In fact if you read the forum rules (and you should since this is one of the forums where they actually matter) you will see that for things like math problems, giving an answer is against the rules.
