Does methane gas stink?

Question

Does methane gas stink?

Answer 1

Reactive with oxygen too.

Answer 2

No.

Pure methane is an odorless, colorless gas. When released by animals it is mixed with various molecules (usually containing sulfur) that produce a scent.

Answer 3

Methane, which is an odorless and colorless gas, is reactive with oxygen?  Really?

If you have a room full of methane and oxygen it will remain a room full of methane and oxygen.   It will stay that way forever, or unless something (a match perhaps) provides sufficient activation energy.

But at room temperature methane does not spontaneously react with oxygen.

Answer 4

it is odorless gas; the smell characteristic of natural gas is an artificial safety measure caused by the addition of an odorant, often methanethiol or ethanethiol.......
