One round from AP Chemistry — Unit 3: Intermolecular Forces and Properties

Four students see

Intermolecular Forces

Attractions occurring between distinct molecules.

The fifth sees

Non-covalent

That is all they get — a hint, not the term the other four are holding — and they have to describe it first.

The Mole knows it is an attraction that is not a covalent bond. They can talk about molecules pulling on each other and sound right — until it slides into the bonds inside a molecule, which is the same word with two letters changed and the opposite answer.

Recognizing a word is not knowing it

Inter and intra differ by two letters and decide whether a student is explaining boiling points or bond energies. A bubbled answer hides which one they meant. A sentence cannot.
