Problem: Benzoic acid is a food preservative. The space-filling model for benzoic acid is shown below.Draw the Lewis structure for benzoic acid, including all resonnance structures in which all atoms have a formal charge of zero

FREE Expert Solution
  • We can make an initial Lewis structure out of the given space-filling mode where benzoic acid appears to have 6 Cs atoms in a ring-like structure with 5 Hs on it. The last C atom has a -CO2H group on it

  • Now account for the electrons in the structure to by determining how many valence electrons are present.

  • C atoms have 4 valence electrons, while H has 1 and O has 6. Total valence electrons are 46 (4(7) + 6(2) + 1(6) = 46)
