3. Consider the real world objects below exterior interior of human of human bod bod A roll of ta A nail A screw Which are chiral, and which are achiral? It is easier to prove an object is achiral than to prove it's chiral. You can prove an object is achiral in two ways a. i. draw its mirror image, and show that the mirror image is superimposable on the original ii. find a plane of symmetry in the original...

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.
