Summary Introduction

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.

Conclusion
Organic compounds are mainly made up of carbon and hydrogen along with oxygen, nitrogen, sulfur, and phosphorus.

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
