He bond dissociation energy of a c-c single bond in a typical alkane is 347 - 377 kj/mol, meaning that to break a mole of such c-c bonds, it requires 347 - 377 kj of energy. this energy can be supplied by heat or by electromagnetic radiation. suppose that we want to break a c-c bond in a specific alkane with a bond dissociation energy of 354 kj/mol by a single photon, calculate the maximum wavelength of this photon. round your answer to three significant figures and units in nm.
