Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

I would also like to make a contribution to this interesting topic  :)

Bicyclobutane, systematically named: bicyclo[1.1.0]butane

This interesting molecule can be made by treating 1-bromo-3-chlorocyclobutane with sodium in refluxing dioxane (see reference below)

Organic Syntheses, Coll. Vol. 6, p.133 (1988); Vol. 51, p.55 (1971).

If there are 4 (and only 4) atoms, in a saturated ring, then you're right, but given the initial question there's nothing wrong with the other answers ;)

Hi sjb I don't understand how the four carbon ring is called dioxane .Please reply

I think from this that we may have caused a bit of confusion folks, so leave off the "extra" answers. Yes, by a strict reading of the question they're correct, but probably not for the best.

Prasannab13, have you searched for all of the structures named - can you see how they all fit a reading of your question?

Dioxane, for instance is at http://en.wikipedia.org/w/index.php?title=1%2C4-Dioxane&oldid=218981715 , or thiophene at http://en.wikipedia.org/w/index.php?title=Thiophene&oldid=212771630
