Please answer the following question: Answer the following question given this paragraph: isolating the individual components, preservationists are better able to determine the condition of an object and those books and documents most in need of immediate protection. The simplest class of organic compounds is the hydrocarbons, which consist entirely of carbon and hydrogen. Petroleum and natural gas are complex, naturally occurring mixtures of many different hydrocarbons that furnish raw materials for the chemical industry. The four major classes of hydrocarbons are the alkanes, which contain only carbonhydrogen and carboncarbon single bonds; the alkenes, which contain at least one carboncarbon double bond; the alkynes, which contain at least one carboncarbon triple bond; and the aromatic hydrocarbons, which usually contain rings of six carbon atoms that can be drawn with alternating single and double bonds. Alkanes are also called saturated hydrocarbons, whereas hydrocarbons that contain multiple bonds (alkenes, alkynes, and aromatics) are unsaturated. Q: The simplest class of organic compounds is the what? Choices: - particles - Phenols - gas - hydrocarbons A:
