2C8H18 + 2502 ---> 16CO2 + 18H20\nit sometimes helps to first solve H then C then O in that order.

The formula in the above answer is incorrect since it omits the aromatic ring and the 9 subsequent repeating units (it's not 9 repeating -OH groups, that makes no sense).\n\nThe empirical formula by my calculations seems to be: C33 H60 O10

CH2O is the empirical formula for a simple sugar, such as glucose.  It is also the empirical formula for many other carbohydrates.\n\nThe molecular formula is always a whole number multiple of the empiracal formula.  For example, C6H12O6 is the molecular formula for glucose, referenced above.

Ok.  Butanal is CH3 - CH2 - CH2 - CH = O.  According to naming scheme, you would have the CH being 1.  Therefore, it is \n\n\nCH3 - CH2 - C(CH3)2 - CH = O\n\nSince I cannot draw it, at the C(CH3) is supposed to signify that on the C there are 2 methyl groups attached.

CH3CH2C(CH3)3.\nI guess you forgot to type the C before the parenthesis. If you didn't forget, then none of the answers is correct (you would be missing a carbon atom).\n\nChem-man I would have contacted you in private about this but you do not give us the option to e-mail you. I have seen several of your answers prompting askers to verify your answer through echemistryhelp. I checked the website and it is not a free one; you post a question and pay for the answer. I'd say that this is a form of indirect advertisement  which is against the community guidelines. Please refrain from doing that or I will have to report you.
