The NMR spectrum of a compound can reveal whether the atoms within the molecule areequivalent 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 hydrogenatoms attached to the same carbon atom are equivalent, but different from the hydrogenatom on the other carbon atom. Predict how many different types of hydrogen atoms canbe identified in the 1H NMR spectrum of each of the following molecules:(а)C2H2(b)cis-C2H2C12(c)trans-C2H2Cl2(d)CH3OHIn the molecule C2H5C1, the hydrogen atoms would all be different if the(e)molecule existed in only one conformation. However, only two types of hydrogen atomsare detected. Propose an explanation.

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. However, only two types of hydrogen atoms
are detected. Propose an explanation.

13C NMR spectroscopy provides valuable information about the environments of a molecule's carbon atoms. Since carbon atoms are often connected to hydrogen atoms, which could split the carbon signal through spin-spin coupling, the coupling between C and H is often "turned off" through the use of broadband decoupling, causing each C signal to appear as a singlet. Draw an isomer of C5H11Cl that would be expected to have four resonances in its 13C NMR spectra.
Chemistry Let ωCH be the angular frequency of the C-H bond stretching vibration observed in theIR spectrum of an organic molecule. (Note that angular frequency ω = 2πν). EstimateωC2H, the bond stretching frequency when 1H is substituted by 2H in the molecule.(Express ωC2H in terms of ωCH).

Infrared spectroscopy is a method that works well in the air, as long as it is dry. What is it about this type of spectroscopy that makes it suitable in O2 and N2 and what is it about water that makes it a problem? (consider each gas in turn and analyse why it absorbs infrared strongly or not, also consider the number of absorbtion wavelengths that a gas might have) If we have a bond that absorbs in the infrared region, such as C=O and we change the groups attached to it so that the bond becomes stronger what would we expect to happen to the infrared absorbtion band?
Q 1(a) Methane, CH4 is a tetrahedral molecule and does not exhibit a permanent dipole moment (i.e. it has a dipole moment of 0). Nonetheless, in microwave spectroscopy methane does exhibit a weak, but measurable absorbance. Explain why you think this is the case? Q 1(b) The diatomic molecule 12C32S has been detected in interstellar gas clouds by microwave spectroscopy. The masses of the two atoms are C = 12.00 amu and S= 31.972 amu and 12C32S has an equilibrium bond length of 1.534 Å. Predict which rotational transition in 12C32S will have the greatest population at a temperature of 85 K.
Vibrational Spectroscopy When an atom in a bond is replaced with a different isotope of the same element, the reduced mass of the bonded atoms change the absorption of the vibration in the infrared (vibrational) spectrum. The wavenumber of a vibration is given by v = ¹, where k = force constant of the bond, μ = 2π reduced mass. Reduced Mass: μ = 1 " where m₁ and m2 are the mass of each attached atom. Assuming the force constant of a particular pair of atoms does not change when one or the other atom is substituted with an isotope, the magnitude of the vibrational shift can be determined from a ratio of the two vibrations.
