A student has acquired an IR spectra of an unknown six-carbon molecule and has determined that it is either 2-hexyne, 1-
hexyne, or 1-hexene. How can the student use their knowledge of IR spectroscopy to determine the identity of the molecule? In
your answer, clearly specify what regions of the IR spectrum the student should look at and what bonds are responsible for the
absorption bands you indicate.

The 7-electrons in this molecule are delocalized over the
entire molecule. The wavelength of maximum absorption in
the UV-visible part of the spectrum in benzene is 255 nm.
Is the corresponding wavelength shorter or longer than
255 nm for naphthalene?
What IR frequencies would enable a chemist to
distinguish between these molecules?

- The NMR spectrum of a compound can reveal whether the atoms within the molecule are equivalent or different. For example, the hydrogen atoms in CH2=CH2 are equivalent: they all exist in an identical environment. However, in CH2=CHCI, the two hydrogen atoms attached to the same carbon atom are equivalent, but different from the hydrogen atom on the other carbon atom. Predict how many different types of hydrogen atoms can be identified in the 1H NMR spectrum of each of the following molecules: (а) C2H2 (b) cis-C2H2C12 (c) trans-C2H2Cl2 (d) CH3OH In the molecule C2H5C1, the hydrogen atoms would all be different if the (e) molecule existed in only one conformation.
