| You really cannot expect people to recognise HC8H4O4.2- as hydrogen phthalate - there are many many possible structures that fit this formula, and unless you can give an accurate structural formula as the clue, you should remove this answer. Hydrogen phthalate = 2-(CO2)C6H4CO2H: you can't really represent it without a drawing!
Also, OH, the hydroxyl radical, is an exceptionally unstable species and it seems a bit of an odd one to put in - maybe use hydroxide instead?
Oh, and I'd probably accept silicon tetrahydride as an alternative to silane! |
