We’re going to use the theory “likes” dissolving “likes” which states that the solvent can only completely dissolve the solute if they share similar polarity.
• Therefore, a pure solvent with similar polarity can successfully dissolve a solute to create a solution.
Intermolecular Forces (IMF) are the attractive forces between 2 molecules.
▪ strongest IMF
▪ deals with the attraction between an ion and a polar compound.
• Hydrogen Bonding
Pick an appropriate solvent(s) from table to dissolve each of the following substances.
|Common polar solvents||Common nonpolar solvents|
|Water (H2O)||Hexane (C6H14)|
|Acetone (CH3COCH3)||Diethyl ether (CH3CH2OCH2CH3)|
|Methyl alcohol (CH3OH)||Toluene (C7H8)|
Express your answer as a chemical formula. If there is more than one answer, separate them by a comma.
Part A. glucose (polar)
Part B. salt (ionic)
Part C. vegetable oil (nonpolar)
Part D. sodium nitrate (ionic)
