Hill notation is a standard way of writing the formula for any chemical compound.
The empirical formula for any compound is written in correct Hill notation.
First, Count All Carbon Atoms and record. C10
Second, Count all Hydrogen atoms and record: C10H23
Third, determine all other elements in compound. Count each and record in alphabetical order. C10H23N
When determining counts from a structural drawing, CAREFULLY count H atoms!!
Counting all the Carbon atoms: C6
Counting all the Hydrogen atoms: C6H18
Determining all the other elements in the compound. Count each and record in alphabetical order.
