A molecular dipole moment is the three-dimensional sum of all the bond dipoles in a molecule. (A_________is a measurable physical property; a________is not measurable, unless the molecule is________)

Answer 1

Answer:

A bond dipole is the unequal charge distribution between two bonded atoms with different electronegativities .A molecular dipole moment is the three dimensional sum of all the bond dipoles in a molecule.(A dipole moment is measurable physical property;a dipole moment is not measurable unless the molecule is polar.

Explanation:

Electronegativity is defined as the ability of an element to attract the electrons that link it to another element.

When two atoms are chemically linked, and their electronegativities are different, the one with the greatest electronegativity will attract electrons towards each other, giving rise to two opposite charges on the bond.

The dipole link moment can then be defined as the magnitude of the polarity in a link. This moment represents the distribution of electronic density in a link. The distribution of charges is due to the fact that the atoms that form them have different electronegativity, so that when a covalent bond is created and the electrons are shared, the two electrons in the bond are attracted with different force by the atoms that share them.

The dipole moment of connection is the product between the value of the charges and the distance that separates them, that is the length of the link. Therefore, a dipole moment is a measurable physical property.

Then the polar bonds are established between atoms of different electronegativity. In a polar molecule there is separation between positive and negative charges. The bonds will be all the more polar the greater the difference in electronegativity between the bound atoms.

On the other hand, the non-polar covalent bond occurs between atoms of the same element or between atoms with very little electronegativity difference. It is thus characterized to molecules or bonds that do not exhibit any polarity. So a dipole moment is not measurable unless the molecule is polar.

Finally:

A bond dipole is the unequal charge distribution between two bonded atoms with different electronegativities .A molecular dipole moment is the three dimensional sum of all the bond dipoles in a molecule.(A dipole moment is measurable physical property;a dipole moment is not measurable unless the molecule is polar.
