What prefix is used in chemistry to denote 'five'?

• A. Tetra
• B. Penta
• C. Hexa
• D. Di

Answer: (B)

In chemistry, the prefix that denotes 'five' is "penta." This prefix is commonly used in the naming of chemical compounds to indicate that there are five of a particular atom or group within the molecule. For example, in the case of pentane, a type of hydrocarbon, the "pent-" prefix signifies that the compound has five carbon atoms in its chain. Understanding these prefixes is crucial in chemistry, as they form the basis for naming various compounds correctly. When you encounter different prefixes, such as "tetra," "hexa," or "di," they represent other quantities (four, six, and two, respectively). Knowing these distinctions helps in interpreting chemical names and formulas accurately.
