I need some help naming compounds with more than one functional group based on their priority order. Here are some examples:
- A 4-membered carbon chain with an aldehyde at one end and a ketone right next to the aldehyde
- A 4-membered carbon chain with an aldehyde at one end, and the ketone and aldehyde having 1 carbon in between.
- A 5-membered carbon chain with a $\ce{C=C}$ double bond at carbon number 2 and a $\ce{C#C}$ triple bond at $\ce{C}_4$ (maybe it is the reverse)
I think that for the one with a double bond and a triple bond, the triple bond gets higher priority and so it would be pent-4-en-2-yne but I am not sure about it.
