How could IR spectroscopy distinguish between 1-hexyne, 2-hexyne, and 3-hexyne? Check all that apply. Check all that apply. 1-Hexyne will show the absorption band at ?2100cm?1 but not the one at ?3300cm?1. 2-Hexyne will show the absorption band at ?2100cm?1 but not the one at ?3300cm?1. 3-Hexyne will show neither the absorption band at ?3300cm?1 nor the one at ?2100cm?1 (there is no change in dipole moment when the C?C stretches). 1-Hexyne will show neither the absorption band at ?3300cm?1 nor the one at ?2100cm?1 (there is no change in dipole moment when the C?C stretches). 3-Hexyne will show the absorption band at ?2100cm?1 but not the one at ?3300cm?1. 1-Hexyne will show absorption bands at ?3300cm?1 for a hydrogen bonded to an sp carbon and at ?2100cm?1 for the triple bond. 1-Hexyne will show absorption bands at ?2100cm?1 for a hydrogen bonded to an sp carbon and at ?3300cm?1 for the triple bond. 2-Hexyne will show absorption bands at ?3300cm?1 for a hydrogen bonded to an sp3 carbon and at ?2100cm?1 for the triple bond. 2-Hexyne will show neither the absorption band at ?3300cm?1 nor the one at ?2100cm?1 (there is no change in dipole moment when the C?C stretches).
