Which statement regarding the interactions of electromagnetic radiation with molecules is correct?
Infrared radiation contains enough energy to cause the homolytic fission of covalent bonds in halogenoalkanes.
Greenhouse gases in the troposphere contribute to global warming by absorbing incoming high-energy ultraviolet radiation from the Sun.
Infrared radiation is used in modern breathalysers to detect and measure the concentration of ethanol in a breath sample.
Absorption of ultraviolet radiation causes covalent bonds within a molecule to vibrate by stretching and bending.
