The average bond enthalpy for c−h is 413 kj/mol. 413 kj of energy is required to break a mole of ch into atoms: ch(g)→c(g)+h(g), δh=413 kj using this information, and your answer from part a, calculate the enthalpy change of the reaction from part b. that is, calculate the energy required to break only the carbon-carbon bonds in benzene. express your answer to four significant figures and include the appropriate units.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
