Question

Why are non-polar substances insoluble in water?

Answer 1

I am not sure whether this statement is correct or not...."Non polar have weak London forces which cannot disrupt the strong hydrogen bonds of water molecules so that's why they are insoluble in water"

Answer 2

@rvc

Answer 3

hey water is a ...................... molecule?

Answer 4

Polar?

Answer 5

can u explain?

Answer 6

Polar molecules dissolve in polar where as non polar dissolves in non polar compounds..but POLAR AND CANNOT DISSOLVE IN NON POLAR......so can we say (in easy words) that non polar doesn't have strong forces to break the forces in POLAR compounds

Answer 7

hey wait

Answer 8

listen

Answer 9

non polar molecules are partially soluble in water
hmmm
let me make it clear
look
ethanol is soluble in water right?

Answer 10

yes??
answer

Answer 11

yes because it contains a hydrogen bond..so it's polar and can dissolve in polar i:E WATER

Answer 12

its has alkyl chain

Answer 13

yes...but a hydrogen bond as well C2H5OH so it has OH (hydrogen bond)

Answer 14

let me give u a lik
for now im quite busy
i hope that works

Answer 15

ok. .thnx for the help :)

Answer 16

;)
os is for that only

Answer 17

read that rn okay

Answer 18

okay :)

Answer 19

when it comes to water
any compound that can form H bond with water will dissolve in water
and only 3 atoms can form H bonds
and those are
Nitrogen, Oxygen, Fluorine
if the other compound has one of these atoms in it
it can form Hydrogen bonds with H atoms of water
and of course
H bonds are stronger than London forces

Answer 20

thnx......so i am correct..

Answer 21

you are welcome :)

Answer 22

@SyedMohammed98 your first comment is right.

The reason being why they don't mix well is because polar molecules have stronger intermolecular attractions (or IMF) toward other polar molecules (they also have IMF with non-polar molecules too but this tends to be weaker). This is why polar molecules tend to be attracted to other polar molecules and push the non-polar components away, so you have this separation of different layers.

Molecules with N, O, and F is a good indicator of miscibility with water, but not always. If you have like a giant molecule with tons of benzene rings (very non-polar) and just one hydrogen bonding site then it'll not dissolve well into water. What matters is the relative RATIO of the non-polar part to the polar part in a molecule. Another example is the phospholipid in your cell membrane. Even though it has a pretty much ionic head it doesn't dissolve in water but instead form balls-like shape (which is ideal as a barrier to hold stuff inside the cell).

Thank you so much Alias
