# Hill's system alphabetizes elements symbol or name? [duplicate]

Take monosodium glutamate. Its chemical formula is $$\ce{C5H8NO4Na or C5H8NNaO4}$$ First way nitrogen, oxygen, sodium, with is in order of element's name. Second way, N, Na, O, in order of element's symbol. Have seen it both ways, hoping someone could clarify. Thanks.

• Organic Chemists have a bias for C, H, N and O, so by habit I tend to write those ones first. I don't actually know the formal rule. – Lighthart Aug 25 '16 at 15:37

In your example $$\ce{C5H8NNaO4}$$ is correct.
