Ultraviolet radiation and radiation of shorter wavelengths can damage biological molecules because these kinds of radiation carry enough energy to break bonds within the molecules. A typical carbon–carbon bond requires 348 kJ/mol to break. What is the longest wavelength of radiation with enough energy to break carbon–carbon bonds?

• A. 3.44×10⁻⁷ m
• B. 5.78×10⁻⁷ m
• C. 7.23×10⁻⁷ m
• D. 8.01×10⁻⁷ m

Answer: (A)
