Question

which is more polar? 4-methylcyclohexanol or 4-methylcyclohexene? And why?

Answer 1

A polar molecule is when it forms an dipole inside it. This because of the difference of the electronegativity between the atoms that share the electron pair. A non polar molecule is when there are no dipole forms in the molecule or there are no free electron pair to share with a solvent.

So because of this characteristics, in the 4-methylcyclohexanol we have an alcohol group, between the oxygen and carbon forms a dipole so the molecule could be polar in a verylow range, because the rest of the molecule doesn´t help with polarity.

The 4-methylcyclohexene is a non polar compound because there is no electronegativity difference between the atoms, and the double bond doesn´t share his electron.
