Geometric isomers and alkenes
Are geometric isomers only possible with alkenes (Z/E isomers) since bonds can rotate with alkanes and are fixed in a straight line with alkynes?

Functional Group Naming
For final grading purposes, should we treat all functional groups with the same priority and number them based on the first letter of the name of each group (ie. alcohol>aldehyde>carboxyl>ether>ketone>triple bonds>double bonds>substituents) or do we number according to the normal list for prioritizi...

Transition State Energies
In a transition state, are the changes in Gibbs free energy and enthalpy always positive relative to the reactants or is it possible for those values to be zero or negative, and if so, how?

Mercury as an electrode
I heard that Hg(l) can be used as an electrode along with Pt and graphite. How would it look like on a cell diagram since it's in liquid form at STP?

Re: Significant Figures and the de Broglie Wavelength Equati
I believe the answer on the solutions page is incorrect. There should be three sig figs.
