Question

For each of the combinations listed below, choose whether it describes a polar molecule or a nonpolar molecule.
All bonds in the molecule are polar, and the molecule is symmetric.

All bonds in the molecule are polar, and the molecule is not symmetric.

Some bonds in the molecule are polar, and the molecule is symmetric.

Some bonds in the molecule are polar, and the molecule is not symmetric.

No bonds in the molecule are polar, and the molecule is symmetric.

No bonds in the molecule are polar, and the molecule is not symmetric

Answer 1

I believe its all about Whether its Symmetric or not
if the molecule IS symmetric - its NON POLAR regardless of the fact that the molecule has polar bonds
if the molecule IS NOT symmetric - its POLAR again regardless of the fact that the molecule has non polar bonds.


"A molecule can possess polar bonds and still be nonpolar. If the polar bonds are evenly (or symmetrically) distributed, the bond dipoles cancel and do not create a molecular dipole. "

Answer 2

@iPwnBunnies im kinda struggling to remember, if the molecule has non polar bonds and is not symmetric - would it be polar?
actually i don't think so myself

Answer 3

now that i thought of it i think Symmetric rule that i just said is about molecule having Polar bonds only <.<

Answer 4

Non-polar bonds? Muh chemistry knowledge is waning...
Shouldn't most bonds be polar, unless it's with of the same element?

Answer 5

hmm but it even has option where some bonds are polar
if some are polar, what are other part of 'some' then ?

Answer 6

I don't know. /).(\

Answer 7

Non-polar
-only non-polar bonds
-polar bonds arranged symmetrically so that the dipoles cancel out

Polar
-A polar molecule has a net dipole.
This is achieved in the molecule by the molecule being made up of polar bonds arranged unsymmetrically so that the dipoles do not cancel out.

Answer 8

polar- asymmetric electron distribution around the molecule, you cannot have a molecule made of the same element because those atoms would have the same electronegativity and electron distribution would be symmetrical. It also depends on the geometrical retricemetry there has to be a dipole a seperation of the charge around the molecule into a more positve area and a negative area

Answer 9

geometrical asymmetry*

Answer 10

ah alright i think i get it
Some bonds polar means some are non polar ~ molecule can be polar or non polar
if its entirely non polar bonds - in that case the whole molecule is NON polar

if the molecule has some/ or is entirely made of polar bonds - then its can be Polar- if molecule is NOT symmetric, and can be Non-polar - if molecule IS symmetric

Answer 11

@iPwnBunnies does it make sense now?

Answer 12

or im still missing out something?

Answer 13

@Abmon98 polar molecule - NOT symmetric electron distribution

Answer 14

yes they are asymmetric

Answer 15

<.< symmetric would mean no net dipole
and its non polar then
@Abmon98

Answer 16

i did say its asymmetric i never said that polar molecules are symmetrical and i know that it would have no net dipole @Somy

Answer 17

oh lol i read it wrong lmao
sorry @Abmon98

Answer 18

its okay :)
