Provide the correct structure for your unknown based on the
spectroscopic data provided. Provide the correct name for your
compound. Either the IUPAC name, or a commonly accepted name (i.e.,
ethyl acetate in place of ethyl ethanoate) will be accepted.IR
spectrum: Assign as many peaks as possible. In particular, you
should assign peaks that were important in making your structural
interpretation (i.e. functional group peaks such as OH, C=O, N-H,
etc.).
1H-NMR spectrum: Assign all the peaks in the spectrum...
this is a road map problem..1st solve for box C using
the HNMR ...and give structure for A-F ..please provide stepwise
mechanisms for this and explanation with electron arrow
pushing...thank you
