2. What is a net dipole? - Socratic

   socratic.org/questions/what-is-a-net-dipole

   Dipole moments occur when there is a separation of charge. This occurs due to an atoms' electronegativity - where one atom has the ability to attract electrons towards it (In other words, electrons wants to spend other time around it) giving it a negative charge and the other a positive charge. Net dipole operates on the same idea - but it ...

3. Dipole-Dipole Interactions - Chemistry - Socratic

   socratic.org/chemistry/intermolecular-bonding/dipole-dipole-interactions

   Permanent dipole-permanent dipole interactions Polar molecules have an asymmetrical electron cloud/charge distribution. This is due to an asymmetrical shape (due to lone pairs of electrons around the central atom) and/or due to the presence of polar-covalent intra-molecular bonds (electronegativity difference between the two atoms of 0.5 ...

4. Dipoles - Organic Chemistry - Socratic

   socratic.org/organic-chemistry-1/lewis-structures-and-bonding/dipoles

   Dipoles occur when there is a relative charge on each side of a molecule induced by the bond electronegativities. Explanation: The dipole moment of an entire molecule is made up of two bond moments -vector quantities having both magnitude and direction. Thus, a measured dipole moment is equal to the vector sum of the bond moments that comprise it.

5. How can I identify dipoles in molecules? + Example - Socratic

   socratic.org/questions/how-can-i-identify-dipoles-molecules

   We indicate a bond dipole by an arrow with a "+" at one end and pointing towards the negative end of the bond. If Δ"EN" < 0.5, we usually say that the bond is ionic. EXAMPLE Identify the bond dipoles on chloromethane, "CH"_3"C"l. Solution The structure of chloromethane is Δ"EN" for the "C-H" bond is 0.4. The "C-H" bond is nonpolar.

6. What are dipole-dipole forces? + Example - Socratic

   socratic.org/questions/what-are-dipole-dipole-forces

   Dipole-dipole forces are the attraction between the positive end of one molecule and the negative end of another. Dipoles form when there is a large difference in electronegativity between two atoms joined by a covalent bond. The atoms share the electrons unequally because the more electronegative atom pulls the shared electrons toward itself. That means that one atom has a partial negative ...

7. How do you calculate the dipole moment of water? - Socratic

   socratic.org/questions/how-do-you-calculate-the-dipole-moment-of-water

   The dipole moment is calculated by looking up the dipole moment contributions from each O−H bond, which are polar, and summing them to get the net dipole. Each contribution is 1.5 D (debyes). The net dipole points through oxygen down the y-axis in the negative direction. Note that the dipole projection along the x directions cancel each other ...

8. Why does PH3 form a dipole dipole? - Socratic

   socratic.org/questions/why-does-ph3-form-a-dipole-dipole

   It forms dipole-dipole because it is a polar molecule. Here is why: PH3 is called phosphine and it is quite toxic and flammable. PH3 must be polar since it is not symmetrical. PH3 has a lone pair and does not have a trigonal planar geometry--for this reason it is not symmetrical. The dipole moment of phosphine is 0.58D which is less than 1.42D ...

9. What is the difference between a dipole and an induced-dipole?

   socratic.org/questions/what-is-the-difference-between-a-dipole-and-an-induced...

   Answer link. It's when a nonpolar molecule is turned into a dipole molecule due to another ionic molecule.Whereas, a dipole is when then molecule already has different charge Say a molecule was balanced due to the combination and placement of the atoms in the molecule. An ionic molecule could come and attract an electron making it a weak dipole ...

10. What are molecular dipoles? - Socratic

    socratic.org/questions/what-are-molecular-dipoles

    Molecular dipoles exist if one or more of the atoms is more electronegative than the other(s) The most common dipole is water. Since O is more electronegative than H the shared electrons tend to be more in the neighbourhood of the O-atom. Since the molecule is 'bent' they tend to be more in the upper part of the figure above. This gives a slight negative charge (called delta-) at the top, and ...

11. How to calculate dipole moment of "NH"_3? - Socratic

    socratic.org/questions/574e9a737c01490306720ea9

    Then we can get its z component, and triple it for the net dipole moment due to the symmetry of "NH"_3. This is because "NH"_3 has a three-fold rotational axis. As a result, we can say that the dipole moment along each "N"-"H" bond is identical. In that case, each "N"-"H" bond dipole moment is based on: vecmu = i cdot qvecr where q is the ...
