Advanced Organic Chemistry Practice Problems 2021 [upd]

One degree of unsaturation. Likely a carbonyl.

: Symmetry is the deciding factor. For instance, in molecules like dioxane or certain ethers, equivalent hydrogens (those that can be swapped by a symmetry operation) produce a single signal. 5. Strategy: The "Cheat Code" for 2-Step Synthesis advanced organic chemistry practice problems 2021

Identify the two sources of failure.
