The correct Answer is:
To solve the question regarding the type of compound formed when cations and anions combine in a crystal, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Cations and Anions**: - A **cation** is a positively charged ion formed when an atom loses one or more electrons. - An **anion** is a negatively charged ion formed when an atom gains one or more electrons. 2. **Combination of Cations and Anions**: - When cations and anions combine, they do so due to the electrostatic attraction between the positively charged cations and negatively charged anions. 3. **Formation of Ionic Compounds**: - The combination of cations and anions results in the formation of an **ionic compound**. In this type of compound, the cation donates electrons to the anion, leading to the formation of a stable ionic bond. 4. **Characteristics of Ionic Compounds**: - Ionic compounds typically form a crystalline structure due to the regular arrangement of ions. - They have high melting and boiling points and conduct electricity when dissolved in water or molten. 5. **Conclusion**: - Therefore, when cations and anions combine in a crystal, they form an **ionic compound**. ### Final Answer: The correct type of compound formed when cations and anions combine in a crystal is **ionic compound**. ---

In cationic polymerizalion, the initiator is an electrophile that adds to the alkene, causing it to become a cation. The Initiator most often used in cationic polymerization is a lewis acid. Such as BF_(3) or AICI_(3) and in anionic polymerization, the iniliator is a nucleophile that reacts with the alkene to form a propagating site that is an anion.
