Why is the dielectric constant value of covalent compounds is low?
because the covalent compounds are non-polar and when they are placed in the electric field so no effect is created on the field.
What are two properties of covalent bonds?
- covalent bonds involve electrons sharing- covalent bond is not so strong as ionic bond
What accounts for the observed differences in the properties of ionic and molecular compounds?
t Answer Well firstly, ionic compounds form from metals bonding with non metals. Molecular/covalent form from non metals bonding with non metals. A strong electrostatic force between ionic compounds results in them having high melting points. A weaker electrostatic force between molecular compounds results in them having lower melting points and thus weaker bonds. Ionic compounds are made up of ions, so will conduct electricity. Covalent compounds only share electrons and so are not ions, and will not conduct electricity.
What is the easiest way to distinguish an ionic compound from a covalent bond?
Covalent compounds have lower melting point and boiling point compared to ionic compounds since their intermolecular forces are weak. covalent compounds do not conduct electricity unlike the ionic compounds since they do not have any charged particles They also have strong bonds within the molecules. so they do not react with other compounds easily. Whereas ionic compounds are more reactive.
Are ionic compounds more likely to dissolve in water than covalent compounds?
Often - yes. the reason they break apart is the hydration energy of the ions- many ionic compounds are soluble in water and dissociate into ions, however there are ionic solids such as CaCO3 which are not soluble. The bonds in covalent compunds are often not broken- for example thise in alkanes. However there are covalent compounds which do react with water and dissolve.

How do you find out if a compound is ionic or covalent?
If a compound is made from a metal and a non-metal, its bonding will be ionic.If a compound is made from two non-metals, its bonding will be covalent. Compounds containing two elements (so called binary compounds) can either have ionic or covalent bonding.
What is the example of binary covalent compounds?
A binary covalent compound is one that contains two substances joined by covalent bonds. For example, two nonmetals often join together to form covalent compounds. So, P2O5 (phosphorus pentoxide) is a binary covalent compound. H2O (dihydrogen monoxide) is another one. This is in contrast to binary ionic compounds, which are salts, and are formed by a metal combining with a nonmetal with ionic bonds.
Why do molecular compounds have low melting points?
The covalent bond is not so strong as the ionic bond.
What best describes the properties of ionic compounds?
There is not a statement available so it is difficult to answer this. Some properties of ionic compounds are high melting points, solid in room temperature, and they are brittle.
Why are properties of different compounds so different from each other?
because not all elements and compounds react with each other

Will water dissolve in ionic or covalent compounds?
Water is a liquid and is usually considered to be the solvent. Water dissolves solutes. Many ionic compounds, but not all, are soluble in water. Water has negative and positive areas on the molecule so it is ideally suited to dissolving the negative and positive ions of an ionic substance. Purely covalent compounds, non-polar, are not supported by water so do not dissolve. Purely covalent, non-polar compounds have no negative and positive areas for the water to support.
