Why is iodine soluble in oil and not water?
The reason the iodine molecules leave water to dissolve in oil is due to how polarity affects solubility. Oil is non-polar; electrons in molecules of this substance are distributed evenly. Iodine is also a non-polar molecule therefore it is more soluble in oil; “like dissolves like”.
Why is iodine soluble in CCl4 and not in water?
Iodine is more likely to dissolve in CCl4(ℓ). I2(s) and CCl4(ℓ) are both non- polar molecular compounds, whereas water is a polar molecular compound. There are no significant attractions between the non-polar I2 molecules and polar water molecules that would cause molecules of I2(s) to separate.
Is pentane soluble in water or oil?

Is water soluble in CCl4?
Chloroform
Which of the following is the most soluble in CCl4?
So, polar solutes are more soluble in polar solvents, while non-polar solutes are more soluble in non-polar solvents. So, looking at your choice of compounds, the non-polar substance will be most soluble in CCl4. That would be the hydrocarbon. All of the other compounds are polar or ionic.
Is Ch3Ch2Ch2OH soluble in water?
Propanol (Ch3Ch2Ch2OH) Is Miscible (soluable) In Water. Butanol (Ch3CH2Ch2Ch2OH) Has A Solubility In Water Of About 9g/100ml.
Which alcohol is not soluble in water?
Because of the strength of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any amount. Starting with the four-carbon butanol the solubility of alcohols is starting to decrease.
Which substance is least soluble in water?
alkane
Which substance is the most soluble in water?
ethylene glycol
How do you know which substance is least soluble?
– To find the least soluble substance at a given temperature we follow the temperature line up and the first substance curve we hit is the least soluble. For most soluble it is the same proceedure except the last substance curve hit is the most soluble.
