Question

question 10
which of the following is not typical of most hydrocarbons?
a poor solubility in water
b low boiling point
c covalent bonding
d high melting point

Explanation:

Hydrocarbons are non - polar molecules. Water is a polar solvent, so hydrocarbons have poor solubility in water (like - dissolves - like principle). Hydrocarbons are held together by weak van der Waals forces. Smaller hydrocarbons have low boiling points. Hydrocarbons are composed of carbon and hydrogen atoms which are bonded covalently. Due to the weak intermolecular forces (van der Waals forces) between hydrocarbon molecules, they generally have low melting points.

Answer:

D. high melting point
