Which of the following statements correctly applies Hückel's rule to the molecules shown below? -CH=CH2 H 2 3 5 O Molecule 2 is not a hydrocarbon; therefore it cannot be aromatic. O Molecule 1 is not monocyclic; therefore it cannot be aromatic. O Molecule 4 is weakly basic; therefore it cannot be aromatic. Molecule 3 is not completely O conjugated; therefore it cannot be aromatic. Molecule 5 has 8 electrons; therefore it cannot be aromatic.
