Question
Which of the following is the empirical formula for hexane, C6H14?
Solution
The empirical formula for a compound is the simplest, most reduced ratio of elements within it.
To find the empirical formula for hexane (C6H14), you need to reduce the ratio of carbon (C) to hydrogen (H) to its simplest form.
- Start with the molecular formula: C6H14
- Divide each subscript by the greatest common factor. In this case, the greatest common factor is 2.
So, divide 6 (the subscript for C) by 2, and 14 (the subscript for H) by 2.
This gives you: C3H7
So, the empirical formula for hexane is C3H7.
