(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.

- 18-17 Hexanoic (caproic) acid has a solubility in water of about 1 g/100 mL water. Which part of the molecule contributes to water solubility, and which part prevents solubility?arrow_forward16-46 Arrange these three compounds in order of decreas ing ability to form intermolecular hydrogen bonds: CH3OH, CH3SH, and (CH3)2NH.arrow_forward16-54 Several poisonous plants, including Atropa belladonna, contain the alkaloid atropine. The name “belladonna” (which means “beautiful lady”) probably comes from the fact that Roman women used extracts from this plant to make themselves more attractive. Atropine is widely used by ophthal mologists and optometrists to dilate the pupils for eye examination. Classify the amino group in atropine as primary, secondary, or tertiary. Locate all stereocenters in atropine. Account for the fact that atropine is almost insoluble in water (1 g in 455 mL of cold water) but atropine hydrogen sulfate is very soluble (1 g in 5 mL of cold water). Account for the fact that a dilute aqueous solution of atropine is basic (pH approximately 10.0).arrow_forward
