Explanation:
The compound that exhibits a sharp band at around 3300 cm^-1 in the IR spectrum is 1-butyne (option C).
IR Spectroscopy:
IR spectroscopy is a technique used to analyze the functional groups present in a compound. It measures the absorption of infrared radiation by the compound, which corresponds to the vibrational frequencies of the bonds.
IR Spectrum of Alkynes:
In the IR spectrum, alkynes typically show a strong, broad absorption band in the range of 3300-2100 cm^-1. This absorption is due to the stretching vibration of the carbon-hydrogen (C-H) bond.
Comparison of the Given Compounds:
To determine which compound exhibits a sharp band at around 3300 cm^-1, we need to compare the structures of the given compounds.
a) 1, 2-butadiene: This compound contains conjugated double bonds but does not have a triple bond. Therefore, it does not exhibit a sharp band at around 3300 cm^-1.
b) 1, 3-butadiene: Similar to 1, 2-butadiene, this compound contains conjugated double bonds but lacks a triple bond. Hence, it also does not show a sharp band at around 3300 cm^-1.
c) 1-butyne: This compound has a triple bond (C≡C) between the first and second carbon atoms. The stretching vibration of the carbon-hydrogen bond in the terminal alkyne group (-C≡CH) produces a strong, sharp absorption band at around 3300 cm^-1 in the IR spectrum. Therefore, option C is the correct answer.
d) 2-butyne: This compound also has a triple bond (C≡C), but it is present between the second and third carbon atoms. The terminal alkyne group (-C≡CH) is absent in this compound. Consequently, it does not exhibit a sharp band at around 3300 cm^-1.
Conclusion:
Among the compounds given in the options, 1-butyne (option C) is the only compound that exhibits a sharp band at around 3300 cm^-1 in the IR spectrum.
The compound that exhibits a sharp band at around 3300 cm^-1 in the IR spectrum is 1-butyne (option C).
