Why is liquid nitrogen used to fast freeze food instead of liquid oxygen? There are two reasons. First, liquid nitrogen is colder than liquid oxygen and thus more effective at flash freezing.
What you have to realize about many of the lighter gaseous elements like oxygen, nitrogen, and fluorine, is that they have lone pair electrons that tend to be very repulsive.

Really the question you should be asking is why the oxygen-oxygen bond is not weaker than it is.
