The answer is visible rays. For example, when a rain storm stops, the sun comes out and you are likely to see a rainbow. This is because the sun shines on water molecules in the air and the colors appear. These colors are called visible light. The only ray that a naked Human eye can see
Answer:
Hydrogen bond is a <em>special type of dipole-dipole interaction between the hydrogen atom in a polar bond, such as N-H, O-H, or F-H, and electronegative O,N or F atom</em>. The interaction is written:
A-B . . . B or A-H . . . .A
A and B represent O,N or F; A-H is one molecule or part of a molecule and B is a part of another molecule, and the dotted represents the hydrogen bond. So, hydrogen bond is a type of intermolecular forces (attractive forces between molecules, <u>NOT</u> between atoms of the same molecule), and only a few elements can participate on hydrogen bond formation.
<em>Note: dipole-dipole interactions are forces between polar molecules, that is, between molecules that possess dipole moments. </em>
Answer: The molecule is expected to have a dipole moment of zero.
Explanation:
The product of magnitude of the charge calculated in electrostatic units is called dipole moment.
Formula for dipole moment is as follows.
Dipole moment = Charge (in esu) distance (in cm)
Non-polar molecules have zero dipole moment.
For example, is a non-polar molecule so its dipole moment is zero.
is a polar molecule so it will have dipole moment.
is a polar molecule so it will have dipole moment.
has nitrogen atom as more electronegative than hydrogen atom. So, net dipole moment will be in the direction of nitrogen atom.
Thus, we can conclude that the molecule is expected to have a dipole moment of zero.
