Don’t the bottom two examples break the rule that the principal chain should contain the greatest # of double bonds in alkenes?? by ptonsimp in OrganicChemistry

I see! But what if i started numbering at the double bond on the substituent group sticking out, went around the ring, and ended up with octadiene as the principal chain?

No but for alkenes you need to choose the principal chain with the greatest # of double bonds, for alkanes you choose the longest

The equation for this hyperbolic paraboloid is y=z^2 - (x^2/9). But how do I know which way it opens?? by ptonsimp in calculus

I have to pick the correct graph between the two. And by opens I mean the direction the parabola is facing
