Cheat Sheet
- Defining Binary Molecular Compounds -
Binary molecular compounds are composed of exactly two nonmetal elements connected by covalent bonds, distinguishing them from ionic salts. These compounds rely on shared electron pairs rather than electrostatic attraction, so they often have lower melting points than ionic compounds (University of Oxford, Inorganic Chemistry). Understanding what is a binary molecular compound is the first step to mastering their formulas and names.
- Binary Compound Naming Rules -
In binary compound naming, use Greek prefixes (mono-, di-, tri-, tetra-, etc.) to denote atom counts, omitting "mono-" on the first element (IUPAC recommendations). For example, CO₂ becomes carbon dioxide and PCl₅ becomes phosphorus pentachloride, making binary compound naming systematic.
- Writing Binary Molecular Compound Formulas -
To write a binary molecular compound formula, reverse the prefixes into subscripts: dinitrogen tetroxide is N₂O₄ and sulfur hexafluoride is SF₆ (MIT OpenCourseWare). A handy mnemonic for the first five prefixes is "My Dad Tried Tacos Previously," linking mono- to penta-.
- Common Binary Molecular Compounds Examples -
Familiarize yourself with examples like carbon monoxide (CO), carbon dioxide (CO₂), and nitrogen trifluoride (NF₃) to see how naming and formulas align in practice (Royal Society of Chemistry). Reviewing binary molecular compounds examples solidifies your command of both formula writing and naming conventions.
- Avoiding Common Pitfalls -
Watch for pitfalls like misplacing prefixes or dropping "mono-" on the first element, and always list the more electropositive element first (American Chemical Society guidelines). Practice by converting between names and formulas - e.g., phosphorus trichloride (PCl₃) ↔ PCl₃ - to build confidence and accuracy.
