Since ethanol is CH3CH2OH, when 1H is taken away, it become ethoxide ion with a negative charge at the end with a formula, CH3CH2O-. Hope this helps!

CH3OOH is methyl hydroperoxide.

C2H5O- could be ethoxide ion (CH3CH2O- ion). No neutral molecule will have the formula, C2H5O.
2xH3 is 6 and 2xH2 is 4, therefore 10. Though CH3CH2O is not a molecule that exists (at least not anywhere near stably).
If mixed, Ethanol and Magnesium will react and form Hydrogen gas and Magnesium Ethoxide. 2 CH3CH2OH(liq) + Mg(s) -> (CH3CH2O)2Mg(s) + H2(g)
Between methanethiol and methanol (if both species remain PROTONATED), I think methanethiol is the better base (ie, it is easier to form CH3CH2SH2+ than to form CH3CH2OH2+) because the lone pairs on the O are closer to the nucleus (O is more electronegative than S), so the O lone pairs are less available to reach out and grab a proton (aka they are less basic).Between the DEPROTONATED forms, methoxide (CH3CH2O-) is definitely more basic than methanethiolate (CH3CH2S-). ?Methanol has a higher pKa than methanethiol by about 5 pH units).

Sodium reacts with Ethanol to produce Sodium Ethoxide (C2H5ONa) and Hydrogen gas (H2), according to the following equation.2 C2H5OH + 2Na ----> 2 C2H5ONa + H2

Acidity depends on the concentration of H+. Due to higher electronegativity of sp2 hybridised carbon of phenol, the electron density on the oxygen decreases and hence increases the polarity O-H making the phenol unstable compared to phenolate, so it is more acidic. The C6H5-group is a fully sp2-hybridised electron pulling group.If you have electron providing groups (sp3) in CH3-CH2-O-H, it may decrease the polarity of O-H bond and destabilize the negatively charged ethanoate group (CH3CH2O-)
ethanol and waterEthanol = C2H6O or CH3CH2OH as is more accurate to its structure. Water = H2OWater and Ethanol, when mixed together, will do almost nothing. However, about 10^-14 %of the time water will react with itself to form H3O(+) and OH(-). At this point the OH(-) will capture the loosely bound Hydrogen from an ethanol molecule. The resulting equation looks like this.CH3CH2OH + H3O(+) + OH(-) = CH3CH2O(-) + H3O(+) + H2Owhere the sign in parenthesis is the formal charge for the molecule. Remember, this only happens around 10^-14 % of the time and is very difficult to measure or even separate from the solution. Most of the time water and ethanol will not react and you'll simply get wet ethanol.
Phenols are much more acidic than alcohols. This is indicated in the order of acidity constant:Ka Gernal formulaPHENOLS 10-10 Ar-OHALCOHOLS 10-18 C-OHPhenols are more acidic due to the formation of phenoxide ions & phenoxide ions are stable due to resonance, the negative charge on oxygen is spread throughout the benzene ring & is delocalised. On the other hand no resonance is possible in alkoxide ions derived from alcohol. The negative charge is localised on single oxygen atom.
