Question

What is the empirical formula for propene (C3H6)?

Answer 1

To determine the empirical formula or the simplest ratio of specific atoms to other atoms in a given compound, simply divide by the largest common divisible factor of the subscripts in this case it's 3.

C3H6 -> CH2.

Answer 2

Answer: The empirical formula for propene $(C_3H_6)[tex] is [tex]CH_2$

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Given : Molecular formula for propene $(C_3H_6)[tex]

Thus the simplest ratio of carbon and hydrogen will be 1: 2 and thus empirical formula for for propene [tex](C_3H_6)[tex] is [tex]CH_2$
