Polar vs nonpolar vs ionic - CHEMISTRY COMMUNITY
2017年11月10日 · An ionic bond is when there is a transfer of one or more electrons from a metal onto a non-metal. The general rule of thumb is that if the difference in electronegativity is greater than 2, then it is ionic. A covalent bond is the sharing of electrons, nonpolar is equal sharing and polar is unequal sharing. If it is less than 1.5, then it is ...

2020年11月19日 · Re: Nonpolar vs Polar covalent Post by madelyn kelly 1I » Sat Oct 23, 2021 2:42 am You can typically find determine the type of bond depending on where the two atoms are found on the periodic table.
Polar, Non-Polar, or Ionic Molecules - CHEMISTRY COMMUNITY
2023年11月10日 · Polar molecules are molecules with different atoms, and whichever atom is more electronegative will have a partial negative charge while the other has a partial positive. Ionic molecules are molecules where the electrons are transferred from which creates an anion and cation, but there is still attractive forces between them.

2019年11月30日 · Re: Polar or nonpolar? Post by Prasanna Padmanabham 4I » Sat Nov 30, 2019 6:31 am I know this video isn't really for the exact same molecule, but they are similar and you can use the same "technique" to analyze the polarity of CH2Br2
COCl2 Polar or Nonpolar? - CHEMISTRY COMMUNITY
2014年11月7日 · The dipoles do not cancel because the electronegativity difference between the C-O atoms and the C-Cl atoms is not the same and the molecule is therefore polar. If all the atoms around the central atom were the same, like BH 3, the molecule would be symmetric and the dipoles would cancel making the molecule nonpolar.
SiO2 Polar or Nonpolar - CHEMISTRY COMMUNITY - University of …
2017年12月10日 · SiO2 Polar or Nonpolar Post by allyz1F » Sun Dec 10, 2017 1:58 am On the midterm there was a question on the bond type (polar, non polar, or ionic) of some molecules, and SiO2 was one of them.
Ionic & Nonpolar/polar - CHEMISTRY COMMUNITY
2017年11月11日 · Ionic vs Covalent: A good rule of thumb to use when determining if a bond is ionic or covalent is to use the difference in the two atoms' electronegativity. If the difference is 2.0 or greater, it is ionic. If it is 1.5 or less, then it is covalent. For values in between 1.5 and 2.0, it is tricky to determine if the bond is ionic or covalent.

2023年11月9日 · Re: can ionic bonds be polar Post by 405957853 3I » Thu Nov 09, 2023 6:58 am Hello, there are some specific instances in which an ionic bond can express polarity, but generally speaking, ionic bonds are nonpolar since the transfer of electrons from one atom to another results in opposite charges.
Polar vs. Nonpolar - CHEMISTRY COMMUNITY - University of …
2021年11月5日 · The main thing for telling if a bond is polar or nonpolar is if there is a electric dipole moment. Electric dipole moments are caused by a strong electronegativity difference between the two bonded atoms (where the electrons are pulled towards one atom because it has a larger electronegativity causing that atom to have a …
Why is CH2Cl2 polar? - CHEMISTRY COMMUNITY - University of …
2021年11月13日 · Molecules arranged in a tetrahedral shape will only be nonpolar if all of the atoms surrounding the central atom are the same. However, because Cl is the more electronegative atom in this case, there will be a dipole moment towards this atom. Looking up the 3D-model of a tetrahedral molecule may help you to visualize why this atom won't be non ...
