![**Title: Understanding Chemical Reactions and Electrophiles**
**Equation Explanation:**
The provided equation is:
\[ \text{CH}_2 = \text{CH}_2 + \text{Br}^+ \rightarrow +\text{CH}_2-\text{CH}_2\text{Br} \]
This equation represents a step in a chemical reaction where a double-bonded carbon molecule (ethylene, \(\text{CH}_2=\text{CH}_2\)) is reacting with a bromine cation (\(\text{Br}^+\)) to form a bromoalkane product (\(+\text{CH}_2-\text{CH}_2\text{Br}\)).
**Educational Content:**
This is a step in a ___ reaction where ___ is the electrophile.
**Choices for Completion:**
- Radical Br\(^+\)
- Polar Br\(^+\)
- Radical CH\(_2=\)CH\(_2\)
- Polar CH\(_2=\)CH\(_2\)
**Analysis:**
The type of reaction and the identity of the electrophile are to be completed by choosing the correct terms from the options provided.
- **Radical** suggests a reaction involving free radicals, which are atoms or molecules with unpaired electrons.
- **Polar** suggests a reaction involving polar molecules, where there is an uneven distribution of electron density.
**Electrophile Identification:**
The electrophile is the species that accepts an electron pair. In this reaction, \( \text{Br}^+ \) acts as the electrophile. Thus, the blank describing the electrophile should be filled with "Polar Br\(^+\)".
Understanding the nature of reactions and the role of electrophiles is crucial in organic chemistry, especially in mechanisms such as electrophilic addition.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F14b6b106-4e8a-4775-9d66-77daef426bbe%2Fb16a6575-0c0c-4f58-8585-2324a9398e32%2Fh59emixg_processed.png&w=3840&q=75)
