Ethanol contains an alcohol group (-OH), which includes hydrogen bonding. Hydrogen bonding is stronger than other IMFs such as Van der Waals forces and Dipole-Dipole.
Ethene only has Van der Waals forces as it is an alkene with only C-H or C-C bonds. These means that the forces are not as strong.
Since ethanol contains hydrogen bonding, it will take a higher temperature in order to break these bonds, and thus results in a higher boiling point than ethene.
<span>D. not enough precipitation is the answer</span>
A polar molecule is when the arrangement of the atoms in molecules are unequal, so one end of the molecule has a positive charge, and the other end has a negative charge.
I believe the third one if i am not mistaken
