Do you have any ideas?  You can start with incidental trivia, that you may know, and see if it gives you some insight.  For example, H2, what is it's boiling point?  You don't have to google that -- hydrogen gas, where would you go, to find a cup of the liquid?  Outside on a chilly day?  Household refrigerator freezer compartment?  Can you infer other answers from the other compounds?

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

What is that?  That is not a stable compound...
