Is an ionic compound a molecular compound?
no, they are two different things. molecular compounds have a lower boiling and melting point relative to ionic.
How do ionic compounds and molecular compounds differ in their relative melting and bioling points?
Ionic compounds have higher melting and boiling points than molecular compounds do. The electronegativity difference in ionic compounds makes their bond much stronger.
How are the melting points and the boiling points of molecular compounds different from ionic compounds?
Ionic bonds are significantly resistant to heat, while molecular bonds are broken more easily with the addition of heat energy. Due to this, ionic compounds have much higher boiling points than molecular substances in most cases.
Why do molecular compounds have low melting points and low boiling points relative to ionic substances?
The melting points and boiling points of molecular covalent compounds (ones with discrete molecules) are lower than ionic solids and giant molecule covalent compounds like (silica, SiO2) because the forces that attract them together in the solid and the liquid states (van der waals, hydrogen bonding and dispersion forces) are weaker than ionic (or covalent) bonds.
Molecular compounds have relatively high boiling points?
false they tend to have low boiling points
Why does 0.300 M KCl have a higher boiling point that 0.500 M glucose?
KCl is an ionic compound and glucose is a molecular compound. Ionic compounds have higher boiling points than molecular compounds.
Molecular compounds boil at much higher temperatures than do ionic compounds true or false?
This is false. Ionic compounds have higher boiling points than molecular compounds. For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
How are the melting points and boiling point of molecular compounds different from ionic compounds?
they have diferent temp. also the ionic compounds dont melt they steam
Why do molecular compounds have low melting points and low boiling points relative to ionic substance's?
The melting points and boiling points of molecular covalent compounds (ones with discrete molecules) are lower than ionic solids and giant molecule covalent compounds like (silica, SiO2) because the forces that attract them together in the solid and the liquid states (van der waals, hydrogen bonding and dispersion forces) are weaker than ionic (or covalent) bonds.
Do simple molecular substances have high or low melting and boiling points?
Yes, molecular solids have relatively low melting points.
Why do nitro compounds have high boiling points in comparison with other compounds of same molecular mass?
Due to strong dipole dipole interaction
How are the properties of molecular compounds poor conducters of electricity?
Because have lower melting points and boiling points
