(a)
Interpretation:
Given statement is true or false has to be indicated.
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.
Chemists initially thought that a “vital force” supplied by the living organism is necessary for the production of organic compound. This was proved wrong when the compound urea was synthesized in the laboratory.
The compounds that are found in the living organisms are still classified as organic compounds even though many are synthesized in the laboratory.
(a)

Answer to Problem 1.1EP
The given statement is false.
Explanation of Solution
Given statement states that the total number of organic compounds exceeds the number of inorganic compounds by a factor of about 2. But 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. Therefore, the given statement is false.
(b)
Interpretation:
Given statement is true or false has to be indicated.

(b)

Answer to Problem 1.1EP
The given statement is false.
Explanation of Solution
Given statement states that chemists believe, a “vital force” is needed to form an organic compound. This was disproved when an organic compound named urea was synthesized in the laboratory. The synthesis of urea was done by Wohler in 1820. Therefore, the given statement is false.
(c)
Interpretation:
Given statement is true or false has to be indicated.

(c)

Answer to Problem 1.1EP
The given statement is true.
Explanation of Solution
Given statement reads that the term org- of the term organic was conceptually paired with the org- in the term living organisms. Even now so many organic compounds are synthesized in the laboratory. Then too the organic compounds are said to be found in living organisms. The term org- was conceptually paired with org- in living organisms. Therefore, the given statement is true.

(d)

Answer to Problem 1.1EP
The given statement is true.
Explanation of Solution
Given statement reads that most but not all compounds found in living organisms are organic compounds. In the living organisms the major constituent is the organic compound only. There will also be few inorganic salts and inorganic compounds that contain carbon such as carbon dioxide. Therefore, the given statement is true.
