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 is the much more polar solvent?
Formamide is the most polar solvent. It has a dipole moment of 3.73 and a dielectric constant of 109. As a comparison, water has a dipole moment of 1.85 and a dielectric constant of 80. The higher the dipole moment value and the dielectric constant, the more polar the solvent. At the opposite, the less polar solvents are hexane, benzene and carbontetrachloride.
What is the oxidation number of carbon in propane?
This value is conventionally considered to be +4, although "oxidation number" is preferably not applied to covalent compounds and substituted by "formal charge".
What is the dielectric value of a 12 percent sodium hypochlorite solution?
6.7
Why doesn't table salt have a solubility product constant?
NaCl dissolve so easily that it is not even given a solubility product constant, as this value ( also known as the Ksp) tells us the solubility for compounds that don't readily dissolve.
Does magnesium nitride have a ionic or covalent bond?
In this case, Mg has a value of 1.3 and N has a value of 3.0, so it is an ionic bond. Ionic and covalent bonds are on a continuum. Some "ionic" compounds are in fact partly covalent because the positive cation (e.g. magnesium) polarizes (attracts the electrons of) the anion forming a stronger bond than if it was 100% ionic. A table of ELECTRONEGATIVITY can help one determine whether a bond is ionic or covalent. The bigger the difference in electronegativity the more ionic the bond.

If the distance between the parallel plate capacitor is reduced to half and a dielectric of dielectric constant k is introduced then how does electric field varies?
From the formula, E = V/d, where V is the voltage and d is the distance, it can be seen that the electric field and the distance are inversely related. Thus, as the distance between the parallel plate capacitors is reduced to half, the electric field is increased twice. Moreover, is a dielectric constant k is introduced, the capacitance will increase. This direct relationship can be seen in the formula, C = [k(Єo)A]/d, where k is the dielectric constant. The lowest possible value of k is 1; and that is when the dielectric is a vacuum. Other dielectric constants are greater than 1, such as teflon which has a dielectric value of 2.1 As the capacitance increases, the electric field also increases. (E = 1/2(CV^2))
What is the relation between Dipole moment and Dielectric constant?
The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability. As the dielectric constant increases, the electric flux density increases, if all other factors remain unchanged. This enables objects of a given size, such as sets of metal plates, to hold their electric charge for long periods of time, and/or to hold large quantities of charge. Materials with high dielectric constants are useful in the manufacture of high-value capacitors.
What is dielectric constant?
A dielectric is an insulating material that does not conduct electricity and is transparent to an electromagnetic field. Dielectric materials are used to separate conducting surfaces such as the plates inside a capacitor, wires inside transformers, electric cable conductors, and elsewhere in the electric industry where electrical separation of charged elements is necessary. The dielectric constant is a ratio of the capacitance of a capacitor in which a particular insulating material is the dielectric, to the capacitance of the capacitor in which a vacuum is the dielectric.

Is hexane more polar than dichloromethane?
hexane has dielectric constant (a measure of polarity) 2.02. This value suggests that it is non-polar.
What is the dielectric value of a 12 percent sodium hypochlorite solution?
6.7
What is a non zero constant?
That means the constant has a value that is different to zero.That means the constant has a value that is different to zero.That means the constant has a value that is different to zero.That means the constant has a value that is different to zero.
What is a value that does not change?
A value that does not change is a constant.
Is the value of soil always constant?
No. The value of soil is not constant.
Why doesn't table salt have a solubility product constant?
NaCl dissolve so easily that it is not even given a solubility product constant, as this value ( also known as the Ksp) tells us the solubility for compounds that don't readily dissolve.
