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 carbon ...continues

drawing the structure of a compound

these are 3 quick problems I am getting stumped on for some reason. I'm also not sure what section to find these in a general organic chemistry book.

Friedel-Crafts Acylation

I have a problem with Fiedel-Crafts reactions and I am not sure of the end results of the product. Could you please explain to me the attached question?

Nitration

Explain why nitration of 1,4-dichloro-benzene yields the mononitro derivative while N,N'-diacetyl-1,4-phenylenediamine forms the dinitro compound. Thanks.

Distinguish pentanal and 2-pentanone, benzyl alcohol and diphenylmethanol

What chemical tests might be used to distinguish between pentanal and 2-pentanone, between benzyl alcohol and diphenylmethanol? I believe that the tests to distinguish pentanal and 2-pentanone can be: NMR spectra, 2,4 dinitrophenylhydrazine test and the tests to distinguish benzyl alcohol and diphenylmethanol can be NMR spec ...continues

nucleophilic aromatic substitution

Show the intermediates including all the resonance hybrid structures for the pentyl anion, that are formed. What products would expect to form and in what ratio. For some reason, I don't believe my reactions are done correctly. Could you please explain it to me the correct way? (please see the attachment)

nucleophilic aromatic substitution

Complete each of the three reactions. Name the expected product. Please see my attempt to answer that question in the attachment and let me know what are the correct reactions.

Haloform reaction

Write a balanced equation for the conversion of C6H5CHOHCH3 to the methyl ketone in the presence of I2 and NAOH. Identify which species is being oxidized and which is being reduced. Any help greatly appreciated.
