Naming Covalent Compounds is a free printable Grade 11 chemistry worksheet for practicing how to name covalent compounds from their chemical formulas and write formulas from compound names. The worksheet contains 20 multiple-choice questions featuring compounds such as dinitrogen trioxide, carbon monoxide, nitrogen triiodide, phosphorus trichloride, and chlorine dioxide. Students use prefixes—including mono-, di-, tri-, tetra-, hexa-, and hepta—to connect the number of atoms with the correct compound name or formula. Because the questions alternate between naming formulas and selecting formulas from names, students practice both directions of this essential chemistry skill. The multiple-choice format also gives learners opportunities to distinguish correct element symbols, subscript placement, word order, and prefix selection from plausible distractors. This worksheet is useful for Grade 11 chemistry practice, independent review, or a quick formative check, and it includes a complete answer key for efficient feedback and grading.

WorksheetsAnswer KeyThis Grade 11 chemistry worksheet uses 20 multiple-choice questions to assess naming covalent compounds from formulas and writing formulas from names. Students apply prefixes such as di-, tri-, tetra-, hexa-, and hepta- to determine atom counts, as in identifying N₂O₃ as dinitrogen trioxide or selecting NI₃ for nitrogen triiodide.
Introduce the worksheet by modeling one naming item and one formula-writing item, emphasizing that students must translate between subscripts and covalent prefixes. Then have students explain why an option such as carbon monoxide matches CO before completing the remaining multiple-choice questions independently. Use the answer choices to discuss element order, subscript placement, and the meaning of prefixes.
Watch for students who reverse the element order, omit a prefix, or choose the wrong subscript—for example, confusing N₂O₄ with a formula beginning with Ni. Students may also select carbon dioxide for CO or overlook the difference between a name and a formula when working through the two-direction multiple-choice items. Review how each prefix maps to the number of atoms and how the chemical symbols are written.
You can assign Naming Covalent Compounds as a printable PDF or as a digital quiz on Wayground. It includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable option can also support schools that want to reduce screen time.
Use the worksheet’s Advanced Settings to adjust font spacing and font size for the 20 multiple-choice items, or enable a dyslexia-friendly font to make the chemical names and answer choices easier to read. You can also translate the worksheet into another language while keeping the naming-and-formula practice format.
