Question

Which compound/s (water, acetone, ethanol, hexane, decane, 1-decanol, sodium chloride, and/or iodine) do you think will be soluble in hexane and explain why. You must discuss intermolecular forces in your explanation.

Answer 1

ANS: • Hexane is NOT soluble in WATER : → Hexane Because has fairly equal distribution charge, so it is of NON-POLAR , whereas WATER US POLAR, o there is nothing that attracts the Hexane and WATER molenile ❤ Also, there are intermolecular forces in water, which are dominated by strong Hydrogen bonds (Two per molende) of the attractions between water molecule, will cause water molecules to stuck together and exclude hexene. oo as a result they both are not soluble u each other • ACETONE is soluble in HEXANE: It is because, Autone has weaker intermolemlar forces, but these forces are stronger than forus. intermolecular of HEXANE 0 ACETONE is not able to exclude HEXANE, and of they both gets meaed. Also the solubility can be explained on of the basis Hedene ENTROPY (disorderness), as we mia with acetone the nature gets cooled to very high value as energy from the surrounding is used to separate ACETONE moleules. ETHANOL is MISCIBLE in HEXANE (NOT fully SOLUBLE): ETHANOL is generally a POLAR molemle, of its hydrosyl ton) gk is more dominant than its no Von

bolar Hydrocarbon end. And the go Hexene is a non-polar Mor - polar Hydrocarbon end to have a certain level of molemle , so of ETHANOL allows risubility with HEXANE. • HEXANE is SOLUBLE in HEXANE: - o both are some molecules, us have -e, both are non-boler molecules soluble in each other some properties, in both are DECANE is SOLUBLE in HEXANE: Because, both are basically the same thing, us, both are simple Hydrocarbons, and we know that LIKE dissolves like, both are NON-polar hydrocarbons, oo both are soluble in each other I I 1- DECANOL is SOLUBLE in HEXANE: 1-decanol is a non-polar molemile, because the carbon and Hydrogen are Symmetre, and also HEXANE S NON-polar o both are soluble in each other & both have LONDON - forces of attraction SODIUM CHLORIDE is NOT SOLUBLE in HEXANE: o. Nace is an IONIC solid in which Na and co ions are packed in a regular array or lattice. HE I SOLUBLE A una ces en TONE

Hexane is a Can't interact so Nace non-polar molecule / solvent with the ons in the e essentially unsoluble and same way , • IODINE is SOLUBLE in HEXANE: IODINE is a non-polar molecule, because IODINE- ITO DINE bond is pure COVALENT bond. And rescare is also a Nor-bolar compound. o. Both are soluble in each other.
