Interpretation:
For distinguishing the pairs (a), (c), (d), (e), (g), and (i) given in problem 2.46, the key IR absorption bands are to be predicted.
Concept introduction:
Infrared spectroscopy is a simple, instrumental technique, which helps to determine the presence of various functional groups.
It depends on the interactions of atoms or molecules with the
The molecules that have dipole moment are IR active and the molecules that do not have dipole moment are IR inactive.
The IR absorption frequency of an alcohol group lies in the range of
For
For
In IR spectrum, for carboxylic acids, both carbonyl and hydroxyl stretching absorption is present.
The IR absorption frequency for the hydroxyl group of carboxylic acid extends from
The IR absorption frequency of secondary amine lies in the range of
The higher the ring strain, the higher will be the stretching frequency.

Which compound in cach part would you expect to have the higher boiling point? Explain your answers. (a) OH or (c) OH or HO (b) (CHN or A factor (in addition to polarity and hydrogen bonding) that affects the melting point of many organic compounds is the compactness and rigidity of their individual molecules. • Molecules that are symmetrical generally have abnormally high melting points. sert- Buryl alcohol, for example, has a much higher melting point than the other isomeric alcohols shown here: OH OH tert-Butyl alcohol (mp 25 "C) Butyl alcohol (mp -00 "C) Isobutyl alcohol sec-Butyl alcohol (mp 108 C) (mp-114 C) о оarrow_forwardDistinguish the characteristic infrared absorption frequencies that would allow you to distinguish the following pairs of compounds.

Name the compounds whose molecular formulae are given in Question 1(a) (i). Which of the compounds, [Cl-Ag-SCN] and [SCN-Ag-CI], is the more stable? Explain your answer. Draw the boundary surfaces of all 3d orbitals and label these orbitals according to the conventional nomenclature. Clearly draw and label the Cartesian axes. Draw the crystal field splitting diagram for a linear compound, e.g. [Cl-Ag-SCN] or [SCN-Ag-CI], aligned along the z-axis. You only need to indicate the order of the individual d orbitals as a function of the energy. Explain your answer.arrow_forwardLook at the three infrared spectra in Figures C to D and answer the following questions (a) Are any of the spectra that of an alcohol? If so, which? What absorption pattern(s) at what wavelength(s) identifies an alcohol? (b) Are any of the spectra that of a compound containing a benzene ring? If so, which? What three absorption patterns at what wavelengths show that a compound has a benzene ring? (c) Are any of the spectra that of a compound containing only carbons and hydrogens? If so, which? Benzene rings contain only carbons and hydrogens. Might the spectrum or spectra you chose for your answer above indicate a benzene ring?
