Answers
The empirical formula of C5H10 is CH2
Explanation:
The empirical formula is the simplest whole number ratio that describes constituent atoms in a species. C5H10 of course can be reduced to CH2.
The molecular formula is always a multiple of the empirical formula (the multiple might be 1). A very useful parameter with molecular formulae is the "degree of unsaturation" concept. An alkane has the general formula CnH2n+2 (this could be the same as the empirical formula!). If presented with a molecular formula CnH2n we would say that this molecule has 1∘ of unsaturation. A degree of unsaturation has a double bond (C=C, C=O, C=N) OR a ring to account for the absence of the 2 hydrogens. Simple acetylenes have 2 degrees of unsaturation.
