I need some help naming compounds with more than 1 functional group. Here are some examples:
A 4-carbon alkane with an aldehyde and a ketone for both the ketone being right next to the aldehyde and the ketone and aldehyde having 1 carbon in between.
A 5-carbon molecule with an $\ce{C=C}$ 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 that the triple bond gets highest priority and so it would be pent-4-en-2-yne but I am not sure about it.
