Examples of polar substances?
How about ethanol, methanol, sugars like glucose, phenol, hydrogen sulfide. There are MANY other polar substances. How about ethanol, methanol, sugars like glucose, phenol, hydrogen sulfide. There are MANY other polar substances.
Why phenol does not dissolve in water when excess?
Phenol (C6H5OH) is more organic and is a covalent compound. The percentage of carbon is more compared to -OH (the polar part). Hence phenol will dissolve in organic solvents and not in water.
Compare the reactivity between ethanol and phenol?
Reactivity in general between the two is quite difficult to compare since the aromatic ring of phenol is able to undergo reactions which ethanol isn't and vice versa. However, there are a number of reactions which can be compared. The first of these is deprotonation, affecting the acidity of the alcohol. Since the subsequent negative charge on the oxygen is stabilised over the benzene ring, phenol is significantly more acid than ethanol (about 100,000 times). Nuclephilic substitution with the alcohol as the nucleophile is likely to be slightly quicker using phenol due to this easier deprotonation creating a stronger nucleophile than the ethanol. Another common reaction is nucleophilic substitution with the alcohol as the electrophile, which occurs fairly easily to ethanol in the presence of an acid. Phenol however, due to its ring, cannot easily react in the same way.
Why does water dissolve more salt than ethanol?
Water is polar, and so is salt (because it's ionic and therefore polar by definition.) So salt dissolves easily in water, because in chemistry, "like dissolves like." Ethanol is non-polar (because it's a hydrocarbon, and they're all non-polar.) So water and ethanol won't dissolve in each other. Nor will ethanol dissolve salt.
Is isopropyl alcohol more polar than glucose?
Yes, Isopropyl Alcohol is a Polar Molecule.
Which is stronger acid ethanol or phenol?
phenol
Why phenol is stronger acid than ethanol?
phenol is aromatic compound stabilized by resonance where as ethanol is aliphatic
What is more polar ethanol or propanol?
Ethanol is more polar. Propanol has three ch3-OH groups which affect the polarity, making it less polar.
What increase absorbance of phenol in ethanol?
Increasing the amount of phenol in the solution

Suggest a chemical test(s) to distinguish ethanol and phenol. Include the reagents reaction conditions and observations. And the equation?
Phenol solution, or phenol directly from the manufacturer?If the phenol is in the form it comes in from the factory, no chemical test is necessary. Phenol is a white crystalline solid.If it's dissolved in water, the easiest test is pH. Phenol solution is more acidic than ethanol. So...whatever you use for a pH test will do ya.

Is ethanol more polar than ethylene glycol?
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.
Why phenol is more acidic than ethanol?
phenol is more acidic because of the benzene ring present in the molecule,when you lose the H form the OH group it is possible to delocalise the charge around the aromatic system due to the pi electron cloud,straight chain alcohols cannot do this so it is less favourable to deprotonate them hance it is easier to deprotonate a phenol,hence we say it is more acidic
Is ethanol silver nitrate a polar solvent?
Ethanol is a polar solvent. Ethanol will dissolve silver nitrate.
What are two tests distinguish between ethanol and phenol?
with water ethanol is soluble while methane is in soluble
Is ethyl acetate polar?
Acetic acid is polar because it is asymmetrical meaning that dipole moment does not get cancel.
