Organic molecules consist mainly of ______ atoms.
- a. carbon
- b. carbon and oxygen
- c. carbon and hydrogen
- d. carbon and nitrogen
Introduction: The molecules that are majorly composed of carbon and hydrogen are classified by chemists as organic molecules. The basis of life is the organic compounds that make it up. Organic chemistry is the study of these compounds. The methodology of synthesis of these compounds is called as organic synthesis.
Answer to Problem 1SQ
Correct answer: The organic compounds are those that consist majorly of carbon and hydrogen atoms. Hence, the correct answer is option c.
Explanation of Solution
Reason for correct answer:
The living organisms are composed of several molecules. They are called as molecules of life. The molecules of life include carbohydrates, fats, proteins, nucleic acids, and many more. They are made of organic molecules, which mainly consist majorly of carbon and hydrogen atoms. The organic molecules also have oxygen, nitrogen, sulphur, and phosphorus atoms in a minor form. These organic molecules are also found in the non-living things.
Option c. is given as “carbon and hydrogen”.
The organic compounds consist mainly of both carbon and hydrogen atoms that are present in different proportions to form various functional groups.
Hence the correct answer is option c.
Reason for incorrect answer:
Option a. is given as “carbon”.
Though the carbon atoms majorly constitute the organic compounds, chemists define organic compounds as those with both carbon and hydrogen atoms. Hence, option a. is incorrect.
Option b. is given as “carbon and oxygen”.
Certain organic molecules like carboxylic acids, carbonyl functions groups, aldehyde groups, and ketone groups contain both carbon and oxygen atoms; oxygen is present in lesser amount than hydrogen. Hence, option b. is incorrect.
Option d. is given as “carbon and nitrogen”.
Certain organic molecules like amino acids, nucleic acids, phospholipids, amides, amines, nitrile, and imine functional groups. Hence, option d. is incorrect.
Hence the options a., b., and d are incorrect.

- San Andreas Transform Boundary Plate Motion The geologic map below of southern California shows the position of the famous San Andreas Fault, a transform plate boundary between the North American Plate (east side) and the Pacific Plate (west side). The relative motion between the plates is indicated by the half arrows along the transform plate boundary (i.e., the Pacific Plate is moving to the northwest relative to the North American Plate). Note the two bodies of Oligocene volcanic rocks (labeled Ov) on the map in the previous page located along either side of the San Andreas Fault. These rocks are about 23.5 million years old and were once one body of rock. They have been separated by displacement along the fault. 21. Based on the offset of these volcanic rocks, what is the average annual rate of relative plate motion in cm/yr?
