The original poster asked for a common household liguid whose MAJOR component is a molecule that has no hydrogen. Some suggestions so far: Ammonia - no. Not only does the molecule (NH3 gas) have hydrogen in it, but the MAIN component of household ammonia (NH4OH solution) is water. Bleach - Also mostly water. It is true that NaOCl has no hydrogen, but household bleach is rarely less than 90% water by weight. Glass - an amorphous solid. The definition of a fluid is a substance which has no definite shape or form, such as a gas or a liquid. If you think glass belongs in that category, try walking through a pane or two. The only answer I could come up with is Freon. Of course, it is arguable whether Freon is a gas or a liquid, but I feel justified by the fact that at any given moment, more than 90% of the Freon in your house is in liquid form. I also feel a little funny about the term "common" as in "common household liquid". After all, most people wouldn't know where to look if you stopped by to borrow a cup... Silicone (grease/oil) might be another answer if it wasn't for the fact that alkyl (methyl) groups are used to prevent crosslinking. Without these "end caps", silicone would be useful for door stops. -- lotto@lhasa.uucp

Freon 12 is CCl2f2 (Dichlorodiflouromethane) Freon 21 is CHCl2F (Dichloromonoflouromethane) Both may be found in houshold refigeration units such as refirgerators or air conditioners. .....Rob@maccs.uucp

Actually glass is a fluid (though not a liquid). The issue (in the case of glass) is wether or not it is crystalline. It is not. Being in a "rigid condition" does not preclude being a fluid. --jeff {*}!linus!faron!jp jpicc@mitre-bedford.arpa
