Which statement about the physical nature of most organic compounds is correct?
AThey are more reactive than inorganic compounds
BThey are mostly soluble in water
CThey have low melting and boiling points
DThey are mainly held by ionic bonds
Answer & Solution
Correct answer: C. They have low melting and boiling points
1. Organic compounds are mostly covalent, not ionic, so rule out option D.
2. They are largely insoluble in water but soluble in organic solvents, so rule out solubility in water.
3. They react slower than inorganic compounds, so they are less reactive.
4. A key listed property is their low melting and boiling points, so that option is correct.
