Molecular Architecture

Like Duolingo, but for Molecular Architecture. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

A short one: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through Engineering the Reaction Path and The Supramolecular Toolkit.

What you'll learn

Key ideas in Molecular Architecture

  • The transition state has a specific geometry distinct from the ground state
  • Maximized non-covalent interactions lower activation energy
  • Geometric complementarity reduces entropic penalty
  • Applying transition state theory to lower activation energy
  • Hammond's Postulate states transition state resembles species closest in energy
  • Endergonic reactions have late transition states
  • Exergonic reactions have early transition states
  • Predicting transition state structure using Hammond’s Postulate
  • Kinetic products form faster due to lower transition state energy
  • Hammond’s Postulate
  • Thermodynamic products are more stable but have higher activation barriers
  • Temperature and reversibility are the primary levers
  • Kinetic vs Thermodynamic control
  • Bulky reagents increase the energy cost of wrong transition states
  • Transition state geometry
  • SN1 transition states involve significant charge separation

Eight weeks. You meant to finish. You didn't.

Tomo gives Molecular Architecture the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
