Yes, Isopropyl Alcohol is a Polar Molecule.
Yes, ethyl alcohol is a polar compound, that is why it dissolves in water.
Ethanol is a polar molecule.
isopropanol/Ispropyl (or called rubbing alcohol) is a solvent that has polar molecules (molecules with a positive charged molecule that sticks to a negative charged molecule). If you sniff a sharpie, it has a sharp, alcohol smell, right? Sharpies have n-propanol alcohol, n-butanol, and diacetone alcohol in them. They have pretty similar structures to rubbing alcohol. All alcohol have polar molecules. There is a "like dissolve like" rule. This means Polar solvent+Polar solvent=dissolve/removal. OR non-polar solvent+nonpolar solvent=dissolve/removal. The closer the types of molecule and chemical make-ups are, the more likely they are to dissolve or be removed.
It is difficult and expensive to refine anything to 100% purity. Best to use 70% as it is just as effective and cost a whole lot less.
It is probaly a tax issue. You can drink Ethanol, is is alkohol that we drink in vodka etc.. However isopropyl alkohol is denaturated ethanol and it is not drinkable. Used in perfume and cleaning things.
Isopropyl is in alcohol. which makes it dissolve. also alcohol dissolves both polar and non-polar substances , and permanent marker is non-polar. which means that it share electrons equally. I hope this helped ;) Further explaination: isopropanol/Ispropyl (or called rubbing alcohol) is a solvent that has polar molecules (molecules with a positive charged molecule that sticks to a negative charged molecule). If you sniff a sharpie, it has a sharp, alcohol smell, right? Sharpies have n-propanol alcohol, n-butanol, and diacetone alcohol in them. They have pretty similar structures to rubbing alcohol. Most alcohol molecules contain hydrogen, oxygen, and carbon. All alcohol have polar molecules. There is a "like dissolve like" rule. This means Polar solvent+Polar solvent=dissolve/removal.

Assuming you mean by fermentation by yeast, one mole of glucose is converted to 2 moles of ethyl alcohol. Molecular weight of glucose is 180, and alcohol is 46. So every 180 masses of glucose could in theory be fermented to make 92 masses of alcohol. Very roughly - one tonne of alcohol from two tonnes of glucose - need it more accurate - the maths is simple enough.........
Isopropyl alcohol
yes isopropanol is non polar while water is polar yes isopropanol is non polar while water is polar
Pure alcohol evaporates faster than pure water. A mixture of the two will slow the evaporation of the alcohol.
Isopropyl alcohol is the common name of 2-propanol. The O in the hydroxyl group is more electronegative than the carbon/hydrogen atoms and exerts a greater pull on the electrons, which results in the slight polarity of the compound.

Isopropyl? There isn't such compound. Maybe isopropanol ? It is an alcohol and it really burns. But there are cheaper materials to use as a fuel and they are way more fit for that.
This really depends on what you need to use these alcohols for. While is isopropyl alcohol is rubbing alcohol used for external purposes, ethyl alcohol is for drinking. So, if its for consumption, then ethyl alcohol is safe to use. Ethyl alcohol also is used in products like cough suppressants and mouthwashes.

It depends how much you think it might have... if it has a lot, it will be flammable, and have a easily identifiable odor (isopropyl alcohol is rubbing alcohol, and ethanol is the alcohol in alcoholic beverages).Small amounts will be harder to test for without doing a more involved chemical test.

GLUCOSE IS VERY DEFINITELY POLAR WITH OH (HYDROXYL) GROUPS ALL OVER IT, WHICH ARE THEMSELVES VERY POLAR. THE MOLECULE IS ALSO VERY UNSYMMETRICAL WHICH TENDS TO MAKE IT POLAR. THE FACT THAT GLUCOSE IS EXTREMELY SOLUBLE IN WATER (ANOTHER POLAR SUBSTANCE) SHOWS THAT GLUCOSE IS POLAR SINCE "POLAR DISSOLVES IN POLAR" AND "NONPOLAR DISSOLVES IN NONPOLAR" (LIKE WAX AND GASOLINE)
