Concept explainers
Interpretation:
Among the given statements, the correct statement concerning organic compounds has to be identified.
Concept Introduction:
Organic compounds are the important basis of life. They include gasoline, coal, dyes, and clothing fibers etc. The compounds that are obtained from living organisms are termed as organic compounds and those obtained from the earth are known as inorganic compounds. Organic compounds are found in earth also apart from living organisms. All the organic compounds contain the element carbon. Urea was synthesized in the laboratory which is an organic compound.
Compounds are classified into organic compounds and inorganic compounds. Approximately there are about 10 million organic compounds but only 1.7 million inorganic compounds. The ratio between organic and inorganic compounds is 6:1.

- Which of the following statements is not true?a. Water is polar.b. Water stabilizes temperature.c. Water is essential for life.d. Water is the most abundant atom in Earth’s atmosphere.arrow_forwardBiochemists use a modified value for standard ΔG values because A. the reagents are not one molar and the pH = 7. B. the concentration of water is not at 1 molar concentration. C. all reagents are not at a 1 molar concentration. D. the pH in living systems is seldom, if ever, near 0.E.
