Which of the following could be an empirical formula?

Question

A. N2O2

B. CH2O

C. C4H10

D. C6H6

Please help, I am in a distance learning program and I don't understand my work. If someone could please explain how they got this answer, I would appreciate it!

Answer 1

B. CH2O

Answer 2

Any that is its simplest ratio, that would be B.

CH2O cannot be simplified to a smaller subscript formula and all the other choices can.

N2O2 's emperical formula is NO

C4H10 's emperical formula is C2H5

C6H6 's is CH

Answer 3

Um i think it's B. empirical formula basically means simplest expression of the relative number of each type of atom in it. N2O2 can be written as NO. C6H6 = CH and C4H10 = C2H5 so answer is B, CH2O. it's a empirical formula for glucose, C6H12O6. Correct me if i'm wrong. Good luck
