Understand determining isomers, HONC 1234 rule, and differentiating molecules based on scent similarity. Explore the impact of bond arrangement on molecular structure.
E N D
Discussion How can you tell whether a drawing represents a new isomer? • How does the HONC 1234 rule limit the number of possible structural formulas?
Notes • If bonds must be broken to change the arrangement of atoms, then the two drawings are isomers. • If simply changing the orientation of the drawing or rotating a bond can produce the two drawings, then they are the same molecule
Check-In • Will any of the molecules below have the same smell? Explain your thinking.
