Methane is CH4 or H-CH3
Ethane is CH3-CH3
When compared to H- (in methane), the CH3- (methyl group in ethane) is more electron donating and hence ethane is more basic than methane.
Water and methanol each have two polar bonds. Water has two O-H bonds while methanol has an O-H bond and a O-C bond. An O-H bond is more polar that an O-C bond because hydrogen is less electronegative than carbon.
Methanol is more volatile than water because methanol has a larger vapor pressure than water.
because methal was formed second so there more active
Methanol is not basic.
water is more poler then methanol.
methanol is a basic compound
Methanol is CH3OH, ethanol is CH3CH2OH. Both are alcohols, ethanol has one carbon more (or a CH2 group more) and is less polar than methanol. Also ethanol has higher boiling point than methanol.
Methanol because the longer the side chains the less polar it becomes
Most salts will dissolve more readily in water than ethanol, so in ethanol the solid can crystallize out at lower concentrations. Also ethanol has the added benefit of being more easily removed by evaporation.
Acetic acid is polar because it is asymmetrical meaning that dipole moment does not get cancel.

Methanol is more polar because is capable of dipole-dipole interactions AND hydrogen bonding while acetone is capable of just dipole-dipole interaction.
Ethanol is polar, as the non-polar OH group still exerts enough force over the rest of the chain to make the entire hydrocarbon dissolve. This trend continues with alcohols with one carbon (methanol) two carbons (ethanol) three carbons (propanol) and four carbons (butanol). However, butanol is only polar when the OH functional group is attached to a secondary carbon (i.e. butan-2-ol) Hexane is always non-polar, as it is a symmetrical hydrocarbon (like most of them) which means that all forces cancel each other out. So ethanol is more polar than hexane.

Methanol because the longer the side chains the less polar it becomes
I do believe that since methanol (CH3OH) is a smaller molecule than ethanol (C2H5OH), and alcohol loses its polarity (and its ability to dissolve polar molecules as well as its own miscibility in water, also a polar molecule) at around 5 carbons or so, then it would follow that perhaps methanol is better at grabbing onto those polar compounds you'd like to extract. Ethanol usually works just fine for long term extraction, and provides a product we can consume.
Acetonitrile is slightly more polar than methanol. This is due to the presence of the C-N triple bond in acetonitrile (CH3CN).
Yes , phenol is more polar than toluene. because ph-OH has more dipole moment than Ph-CH3
Ethylene glycol is more polar than ethanol - a rough measure of polarity is given by the dielectric constant. For example, water is 80, ethylene glycol 37, and ethanol 24.3. Water is the most polar, followed by ethylene glycol and ethanol. Another way to think about it is that ethanol has one alcohol group, and ethylene glycol has two, so it is more polar.
Butanol, being an alcohol, is slightly polar. The C-O-H bonds are responsible for that. O being more electronegative pulls electrons towards itself from C and H atoms. However, it is less polar than methanol or ethanol.

Potassium fluoride (KF) is soluble in alcohols such as methanol (CH3OH), ethanol (C2H5OH), and isopropanol (C3H7OH). It forms strong hydrogen bonds with the oxygen atoms in the alcohol molecules, allowing for solubility.
