(a)
Interpretation:
The strongest acid among the following should be identified:
CH3 OH, CH3 SH, (CH3 )2 NH.
Concept Introduction:
The acidity of any compound is higher when the compound has a higher electron withdraw or a higher proton donating capacity.
(b)
Interpretation:
The strongest base among the following should be identified:
CH3 OH, CH3 SH, (CH3 )2 NH.
Concept Introduction:
The basicity of any compound is higher when the compound has a higher electron donating ability or a higher proton accepting capacity.
(c)
Interpretation:
The compound with highest boiling point should be identified:
CH3 OH, CH3 SH, (CH3 )2 NH.
Concept Introduction:
The temperature at which the system changes its state from liquid to vapor is known as boiling point. It depends on the size and bonding within the molecules. Higher the size, higher will be the boiling point. Also, stronger the intermolecular interaction within in the compound higher will be the boiling point.
(d)
Interpretation:
The compound with the strongest intermolecular hydrogen bonds in the pure state should be identified.
Concept Introduction:
A hydrogen bond is formed when hydrogen atom bonded with an electronegative atom interacts weakly with other electronegative atom which is present in the vicinity of another electronegative atom.

- 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. Predict the molar absorptivity of transferrin. Predict the absorbance of a solution that’s 1.000 g/L transferrin in a 1.000-cm-pathlength cuvet.
