Question: Which bond type is soluble in alcohol?
1. Metallic
2. Ionic
3. Polar
4. Covalent or Nonpolar Covalent Bonds
Answer: Polar bonds are soluble in alcohol. Alcohol is a polar solvent, and like dissolves like. Therefore, polar bonds, which have a slight positive and negative charge, can dissolve in alcohol due to the similar polarity.
Question: Which bond type has hard, brittle crystals?
1. Ionic
2. Covalent
Answer: Ionic bonds have hard, brittle crystals. Ionic compounds form a crystal lattice structure where positive and negative ions are held together by strong electrostatic forces. This structure makes them hard but also brittle, as the layers of ions can shift and cause the crystal to break when force is applied.
