The mass spectrum of an organic compound shows the relative abundances of M to be 83.79% and M 1 to be 13.59%. Assuming the peaks are caused by 12C and 13C isotopes, determine the number of carbon atoms in the compound. Natural abundances: 12C is 98.93% and 13C is 1.07%
Choose two functional groups and for each group find a household product that contains the group. Then explain the action of the product in terms of the intermolecular forces that these groups impart to the molecule.
