Sorry if this is in the wrong forum, I figured it's not really an organic question, more a nomenclature question...

Anyway, I was wondering how alkane, -ene and -yne work on carbon chains.

If a parent carbon chain had single, double and triple bonds, would it be;
- broken down into smaller substituent groups
- just simply be called an -yne

Does the largest bond in the parent define the parents suffix?

Does the largest bond in the parent define the parents suffix?

Yes.  Alkyne first, then -ene, then -ane.
