Final answer:
OPTION A
OPTION D
The property not typical of most hydrocarbons is a high melting point, as they generally have low melting points. Hydrocarbons also exhibit poor solubility in water and covalent bonding. Organic chemistry focuses on the study of carbon-containing compounds.
Step-by-step explanation:
The answer to which of the following is not typical of most hydrocarbons is A) high melting point. Typically, hydrocarbons have low boiling points and melting points, are poorly soluble in water due to their nonpolar nature, and exhibit covalent bonding. For example, decane, a hydrocarbon with the formula C₁₀H₂₂, has a melting point of around -30°C and a boiling point of approximately 174°C, indicating that it does not possess a high melting point.
Additionally, organic chemistry is the study of compounds containing D) carbon. This branch of chemistry focuses on carbon-based compounds, which are central to all living organisms and include a vast range of substances from simple hydrocarbons to complex biomolecules.
