Answer #1

Always remember that polar compounds & ionic compounds dissolved in polar solvents like water.

Non-polar compounds and covalent compounds dissolved in non-polar solvents like hexane.

CH3CH2COCH2CH2CH3 ----> polar compound ----> soluble in water

Mg(NO3)2 ---> ionic compound ---> soluble in water

CH3COOH  ---> polar compound ---> soluble in water

C6H6CH3  ---> non-polar compound ---> soluble in hexane

LiBr ---> ionic compound ---> soluble in water

HBr  ---> covalent compound ---> soluble in hexane

KClO4 --->  ionic compound ---> soluble in water

CH3OH  ---> polar compound ---> soluble in water

O2 ----> non-polar solvent ---> soluble in hexane
