determine the functional group from the following spectra

I am having trouble with determining the functional group from a specific spectra. This is new to me and Ive never really seen problems like this.

Cyclic Alkyne reaction with KMnO4 and O3

Hello, I am having trouble predicting the products with a cyclic product and alkyne off the side. Here are two I could use some help with. 5 carbon ring, carbon 1 has a carbon attached which also is triple bonded to another carbon (this end carbon just has a H attached.) There is also a double bond between carbons 1 and 2 in the ring. I need to be able to predict the product when this reacts with KMnO4 in H30+. I know that CO2 (I think) is produced but I am having trouble predicting what else will be produced. Here is my best graphical representation of the molecule. 5 carbon ring (single bond) C (triple bond) C (single bond) H Also, there is a double bond in the rin... click for more
