Concept explainers
(a)
Interpretation:
To determine if all organic compounds contain one or more atoms of carbon or not.
Concept Introduction:
The organic compounds are the chemical compounds that includes a huge class of gas, liquid and solid molecules that consists of one or more carbon atoms which are linked by covalent bond to other atoms.

Answer to Problem 1P
One or more carbon atoms are present in all the organic compound. Thus, the statement is true.
Explanation of Solution
The carbon can form strong bonds with other atoms in an organic compound. The organic compounds are chemical compounds for the living things and they have the carbon atoms. These carbon atoms form a bond that are strong and can link with four atoms of other molecules.
(b)
Interpretation:
To determine if the majority of organic compounds are built from carbon, hydrogen, oxygen and nitrogen.
Concept Introduction:
The organic compounds are the chemical compounds that includes a huge class of gas, liquid and solid molecules that consists of one or more carbon atoms which are linked by covalent bond to other atoms.

Answer to Problem 1P
The majority of all the organic compounds are formed of carbon, hydrogen, oxygen and nitrogen. Thus, the statement is true.
Explanation of Solution
The carbon atom can form string bond which are stable with the other atoms of hydrogen, oxygen and nitrogen. The carbon present in all the organic compounds form a strong stable bond with the atoms of nitrogen, hydrogen and oxygen.
(c)
Interpretation:
To determine if the carbon atom is abundant in earth’s crust.
Concept Introduction:
The organic compounds are the chemical compounds that includes a huge class of gas, liquid and solid molecules that consists of one or more carbon atoms which are linked by covalent bond to other atoms.

Answer to Problem 1P
The carbon atom is not the abundant element present in earth’s crust. Thus, the statement is false.
Explanation of Solution
The carbon is present in the atmosphere widely in the form of carbon dioxide but in the earth’s crust it is only of 0.18%.
The carbon is present in the nature only as a combined element and in the earth’s crust it is only in minimum amount when compared to silicon and oxygen.
(d)
Interpretation:
To determine if the organic compounds are soluble in water.
Concept Introduction:
The organic compounds are the chemical compounds that includes a huge class of gas, liquid and solid molecules that consists of one or more carbon atoms which are linked by covalent bond to other atoms.

Answer to Problem 1P
Most of the organic compounds are insoluble in water. Thus, the statement is false.
Explanation of Solution
Most of the organic compounds are insoluble in water as these compounds are non-polar on nature. The organic compounds are non-polar, and water is a polar solvent.

- 5. Propose a Synthesis for the molecule below. You may use any starting materials containing 6 carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not count towards this total, and the starting material can have whatever non-carbon functional groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and III. Your final answer should show each step separately, with intermediates and conditions clearly drawn.

- The molar absorptivity of a protein in water at 280 nm can be estimated within ~5-10% from its content of the amino acids tyrosine and tryptophan and from the number of disulfide linkages (R-S-S-R) between cysteine residues: Ε280 nm (M-1 cm-1) ≈ 5500 nTrp + 1490 nTyr + 125 nS-S where nTrp is the number of tryptophans, nTyr is the number of tyrosines, and nS-S is the number of disulfide linkages. The protein human serum transferrin has 678 amino acids including 8 tryptophans, 26 tyrosines, and 19 disulfide linkages. The molecular mass of the most dominant for is 79550.
