If a substance dissolves in H2O, would it be a polar or non polar?explain?
The simple answer is that like dissolves like: polar dissolves polar and non-polar dissolves non-polar. More specifically: water, H2O, is a polar structure because of its bent shape and, of course, the electronegativity of oxygen, which is far stronger than that of hydrogen. Therefore, a dipole is created, making this oxygen partially negative (since it “pulls” electrons towards itself) and the hydrogens partially positive (for the same reason). This is polarity. Solubility is determined by polarity because of the interaction of molecules. Suppose you have methanol (CH3OH), also a polar structure. In water, CH3OH will interact with H2O. Recall that oxygen is partially negative and hydrogen is partially positive (this is true in both molecules). Hence, oxygen and hydrogen molecules will attract intermolecularly. This is known as hydrogen bonding. (NOTE: it is not a bond, it is an attraction!). The attractions between partially negative and partially positive groups (polar) are what allo
