Which bond type is soluble in alcohol?
Metallic, ionic, polar covalent, or nonpolar covalent bonds?
Which bond type has hard, brittle crystals?
(I think the second is ionic, but not positive.)

Answered above or below, I don't know which but for the sample poster.
Ionic bonds are soluble in alcohol.
The bond type that has hard, brittle crystals is indeed ionic.
To determine which bond type is soluble in alcohol, we need to understand the nature of the different bond types.
Metallic bonds: These bonds occur between metal atoms, where electrons are delocalized and shared among all the atoms. Metallic bonds are not typically soluble in alcohol.
Ionic bonds: These bonds occur between a metal and a nonmetal, resulting in the transfer of electrons from one atom to another. Ionic compounds form when positive and negative ions are attracted to each other. They usually have high melting points and are often soluble in polar solvents like water, but not necessarily soluble in alcohol.
Polar covalent bonds: These bonds occur when atoms share electrons unequally, resulting in the formation of polar molecules. Polar covalent compounds can have varying solubility in alcohol, depending on the specific compound.
Nonpolar covalent bonds: These bonds occur when electrons are shared equally between two atoms, resulting in nonpolar molecules. Nonpolar covalent compounds tend to be insoluble or only slightly soluble in polar solvents like alcohol.
Now, let's consider which bond type has hard, brittle crystals. This property is commonly observed in ionic compounds. In ionic bonding, the strong electrostatic forces between positively and negatively charged ions result in the formation of a crystal lattice structure. The arrangement of ions in the lattice contributes to the hardness and brittleness of these compounds.
In conclusion, the bond type that is likely soluble in alcohol is polar covalent bonds, while the bond type associated with hard, brittle crystals is indeed ionic bonds.
