sites.google.com/.../properties-of-alcoholsAlcohols burns in oxygen to produce carbon dioxide and water. Alcohols burn cleanly and easily, and does not produce soot. It becomes increasingly more difficult to burn alcohols as the molecules get bigger. The general molecular equation for the reaction is: C n H 2n+1 OH + (1.5n)O 2 → (n+1)H 2 O + nCO 2 e.g. combustion of ethanol:

/.../v/properties-of-alcoholsLet's start with physical properties of alcohols. And so we're going to compare, in this case, alcohols to alkanes And this alkane on the left here, two carbons, so this is of course ethane. On the right, if we take off one of those hydrogens and replace it with an OH, we of course have ethanol right here. So let's start with the boiling point.

alcohols-strong-bases-when-they-have-a-pKa-of-approx-16See all results for this question Why are alcohols considered less acidic than water? Alcohol (ROH) is less acidic than water (H2O) because the alkoxide ion RO- is less stable than hydroxide ion HO-. It can be explained by the +I effect of the R group & the hyperconjugation of the α-hydrogens (if any). These effects destabilizes tge alkoxide ion. Why alcohol is more acidic than water? - Quora
/science/alcohol/Esterification CachedAcidity of alcohols: formation of alkoxides. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O −).

/.../reactions-of-alcohols CachedThe acidity of alcohols decreases while going from primary to secondary to tertiary. This decrease in acidity is due to two factors: an increase of electron density on the oxygen atom of the more highly‐substituted alcohol, and steric hindrance (because of the alkyl groups, which inhibit solvation of the resulting alkoxide ion).
CachedHow do we know carboxylic acids are more acidic than alcohols? Carboxylic acid reacts with Na, NaOH. But alcohols only reacts with Na. Carboxylic react with Na 2 CO 3 and NaHCO 3.
