Summary Introduction

Introduction:

Organic molecules are referred to the molecules of life. These organic molecules are made up of carbon atoms. Carbohydrates, lipids, nucleic acids and proteins are four different types of organic molecules.

Answer to Problem 1SA

Correct answer:

Organic compounds are those compounds which are mainly made up of carbon and hydrogen atoms. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Option c. is given as “carbon and hydrogen.”

Carbon atoms can assemble to form different types of compounds because of their versatility. The compounds which are mainly made up of carbon and hydrogen atoms are known as hydrocarbons, and these are said to be organic.

Reason for incorrect answer:

Option a. is given as, “carbon.”

Organic compounds are made up of mainly hydrogen and carbon atoms. Carbon can bond with another carbon molecules, but hydrogen is the main partner of carbon atom in organic compounds. Hence, option a. is incorrect.

Option b. is given as, “carbon and oxygen.”

Carbon and oxygen atoms can bond with each other to form organic compounds, but the atom which is mainly involved in organic compounds is hydrogen. Hence, option b. is incorrect.

Option d. is given as, “carbon and nitrogen.”

Carbon and nitrogen form different types of organic compounds such as proteins. The nitrogen atom is not mainly involved to make organic molecules. Hence, option d. is incorrect.

Hence, the options a., b., and d. are incorrect.

Conclusion

Therefore, organic molecules consist mainly of carbon and hydrogen atoms. Thus, the correct answer is option c.
