Give systematic names for the following compounds: (a) Ca(ClO)₂

검증된 단계별 안내

Identify the cation and anion in the compound. The cation is calcium (Ca) and the anion is hypochlorite (ClO^-).

Determine the charge of the cation. Calcium (Ca) is in group 2 of the periodic table and typically forms a +2 charge.

Determine the charge of the anion. Hypochlorite (ClO^-) has a -1 charge.

Combine the names of the cation and anion. Since the charges balance each other out (Ca^2+ and 2 ClO^-), the compound is named calcium hypochlorite.

Write the systematic name of the compound: calcium hypochlorite.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Ionic Compounds

Ionic compounds are formed from the electrostatic attraction between positively charged cations and negatively charged anions. In the case of Ca(ClO)₂, calcium (Ca²⁺) acts as the cation, while hypochlorite (ClO⁻) is the anion. Understanding the nature of these ions is essential for naming the compound systematically.

Systematic Naming Conventions

Systematic naming conventions, such as those outlined by the International Union of Pure and Applied Chemistry (IUPAC), provide a standardized method for naming chemical compounds. For ionic compounds, the cation is named first followed by the anion. In this case, the systematic name for Ca(ClO)₂ is calcium hypochlorite.

Polyatomic Ions

Polyatomic ions are ions composed of two or more atoms covalently bonded together, which carry a net charge. The hypochlorite ion (ClO⁻) is an example of a polyatomic ion. Recognizing polyatomic ions is crucial for correctly identifying and naming compounds that contain them, such as in the case of calcium hypochlorite.
