Question
a. Naphthalene is a white volatile, solid polycyclic hydrocarbon used in moth balls and repellents.
Looking at the structure of naphthalene given below, determine if it is aromatic or not. Explain
the reasons for your answer?
b. The table below shows the boiling point points of an alkane and aldehyde and an alcohol:
Molecule
CH3CH₂CH3
CH3CHO
CH3CH₂OH
i.
ii.
iii.
Туре
Alkane
Aldehyde
Alcohol
Boiling point (°C)
-42
+21
+78
Why is the boiling point of the aldehyde greater than that of the alkane?
Why is the boiling point of alcohol the highest?
Explain why the solubility of aldehydes and alcohols falls as the molecules get bigger.
