No, a brittle compound does not necessarily indicate it is a molecular compound. Brittle compounds can be either molecular or ionic, depending on their chemical bonding. Brittle molecular compounds typically have covalent bonds, while brittle ionic compounds have ionic bonds.
NaCl
four properties of ionic compound are: 1-All ionic compounds form crystals 2-Ionic compounds are very hard and very brittle 3-Ionic compounds conduct electricity when they dissolve in water 4-Ionic compounds tend to have high melting and boiling points and 3 ionic compounds are: Sodium Chloride - Na Cl Potassium Fluoride - KF Magnesium Chloride - MgCl2
Ionic compounds are generally brittle because the ionic bonds within them are strong and rigid. When a force is applied, the layers of ions in the crystal lattice can shift and become misaligned, causing the structure to break instead of bending.
Water and sodium chloride are ionic compounds.
Ionic compounds are typically hard and brittle due to their strong ionic bonds. The ions in an ionic compound are held together by strong electrostatic forces, making them rigid and resistant to deformation.
NaCl is an ionic compound. Na ions are positive charged and Cl ions are negative charged. A Coulomb force is existing between the two kinds of ions, making NaCl an ionic compound.
some compounds are composed of molecules bound by ionic compounds so no
Ionic compounds are brittle because their strong ionic bonds hold the ions in a rigid lattice structure. When a force is applied to the crystal structure, the ions of the opposite charge align and repel each other, causing the crystal to shatter.
An example is the precipitation reaction with silver nitrate: NaCl + AgNO3 = NaNO3 + AgCl(s)
Ionic compounds are found very frequently in living systems. All of the salt, buffers, blood, etc. contain ionic compounds such as NaCl, KCl, Na3PO4, CaCl2, MgSO4, and on and on.
These two compounds doesn't react.
