Acid-catalyzed dehydration of 3,3-dimethyl-2-butanol yields two compounds A and B, each having a molecular formula C6H12. The 1 H NMR of compound A shows a single peak at d = 1.64 ppm whereas the 1 H NMR of B has more than one peak. Suggest structures for compounds A and B and write a reasonable curved arrow mechanism for the formation of each.

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
