Question 1

It is a branch of chemistry that involves the study of organic carbon compounds; the structures, composition, and synthesis of carbon-containing compounds.

Answer 1

oragnic chemistry

Question 2

True or false: All organic molecules consist only of carbon.

Answer 2

False

All organic molecules consist of carbon-hydrogen/hydrocarbon bonds)

Answer 6

covalently

Question 7

What other forms can carbon atoms bond together apart from chain structures?

Answer 7

• rings
• spheres
• tubes

Question 8

What is the importance of biochemistry in daily life?

Answer 8

They are important in the creation of a long list of products used to support life and to make it more convenient

Question 9

In what ways does the study of organic chemistry impact society?

Answer 9

They are the key in the development of new products and improving those on which we’ve become dependent on.

• improving medicines
• aiding agricultural growth
• understanding the human body
• performing coutnless tasks vital to humans

Question 10

In 1923, Oparin states that organic chemistry may have had its beginning with which cosmic phenomenon?

Answer 10

the big bang

Question 11

According to Oparin (1923), four components were combined to form amino acids which led to paved the origins of organic chemistry (from the big bang).

Answer 11

• ammonia (NH3)
• nitrogen (N)
• carbon dioxide (CO2)
• methane (CH4)

Question 12

When was the experiment, that verified the combination of chemical components during the big bang, finally held to proof?

Answer 12

1950
Miller

Question 13

Organic compounds were used as dyes, medicines, and poisons by these people in ancient times.

Answer 13

Romans and Egyptians

Question 14

Specify the years and contributing authors/minds behind each.

What significant contributions were made in the 16th century for the furtherance of the field of biochemistry?

Answer 14

• Scheele, 1769: organic compounds were isolated from nature in the pure state
• Lavoisier, 1784: analytical methods were developed for determination of elemental compositions

Question 15

In which year did Lavoisier develop anayltical methods for the determination of elemental compositions?

Answer 15

1784

Question 16

In which year did Scheele mention the organic compounds were isolated from nature in the pure state?

Answer 16

1769

Question 17

Who mentioned, in 1807, that organic chemicals found in nature contained a special component that directed their natural synthesis?
- Identify the author and the said special component.

Answer 17

Berzelius
[Jöns Jacob Berzelius]
vital force

Question 18

Who is the man that discovered urea, a natural component of urine, could be synthesized in the laboratory by heating a certain chemical compound in 1828?
- Identify the chemist’s name as well as the chemical compound’s.

Answer 18

Friedrich Wöhler
ammonium cyanate

Question 19

What did the discovery by Wöhler suggest?

Answer 19

It meant that the natural “vital force” was not required to synthesize organic compounds. Essentially, organic compounds can be sourced from both organic and inorganic substances.
