A. Polarity
B. Volatility
C. Flammability
D. Reactivity

Explanation

To complete the statement "Introducing a halogen atom into an alkene can generally reduce its...", we need to analyze the effects of adding a halogen atom to an alkene.

### Step-by-Step Solution:

1. **Understanding Alkenes**: Alkenes are hydrocarbons that contain at least one carbon-carbon double bond (C=C). They are generally more reactive than alkanes due to the presence of this double bond.

2. **Introduction of Halogen**: When a halogen (such as Cl, Br, or I) is introduced into an alkene, it typically reacts with the double bond. This reaction is known as halogenation.
