Which of the compounds c4h10, bacl2, ni(no3)2, sf6 are expected to exist as molecules? which of the compounds c4h10, bacl2, ni(no3)2, sf6 are expected to exist as molecules? bacl2 and ni(no3)2 c4h10 and sf6 only c4h10 c4h10, ni(no3)2, and sf6?

Answer 1

c4h10 and sf6 only Let's look at each compound and see if it works. c4h10 - This looks like a standard hydrocarbon. So it's a molecule. BaCl2 - This looks like it's likely to be a salt, So it's an ionic compound, not a molecule. Ni(NO3)2 - This is a nitrate. So it's a kind of salt. See BaCl2 above. SF6 - Sulfur hexafluoride. It's a molecule.
