Is phenol more acidic than ethanol?
Phenoxide ion is aromatic and can undergo resonance but ethoxide ion can’t. Phenol is more acidic than that of ethanol because phenoxide ion is stabilized through delocalisation. An acid loses H+ ions in water. When phenol loses an H+ ion, the ion formed is known as phenoxide ion.
Which is more acidic out of water ethanol and phenol and why?
Water with a pH greater than ethanol is more acidic than ethanol. The phenoxide ion obtained after the removal of a proton is stabilised by resonance whereas the ethoxide ion obtained after the removal of a proton is destabilised by the effect of — C2H5 group. Therefore phenol is a stronger acid than ethanol.
Which is more acidic between alcohol and phenol?
Phenols are stronger acids than alcohols, but they are still quite weak acids. A typical alcohol has a pKa of 16–17. In contrast, phenol is 10 million times more acidic: its pKa is 10. Phenol is more acidic than cyclohexanol and acyclic alcohols because the phenoxide ion is more stable than the alkoxide ion.
Why phenol is acidic but not ethanol?
Hint: Phenol loses its hydrogen ion to form the phenoxide ion which resonates and stabilizes itself and this loss of electrons makes the phenol more acidic than alcohol for example ethanol.
What is the pH of alcohol?
Is alcohol alkaline?
| Drink | pH | Where it falls on the scale |
|---|---|---|
| vodka | 6.0–7.0 | slightly acidic to neutral |
| gin | 3.0–6.0 | acidic |
| rum | 4.5–5.0 | acidic |
| whiskey | 3.68–4.78 | acidic |
Why phenol is more acidic than ethanol explain?
What is the correct order of acidity of alcohol water and phenol?
Increasing order of acidity is ethanol < water < phenol.
Why phenol is acidic while alcohol is neutral?
Answer: The explanation of the phenol acidity is the resonance stabilization of the phenoxide anion by the aromatic ring. In case of ethanol, ethoxyanion doesn’t have such resonance stabilization and electron density withdrawal from the atom of oxygen, that’s why it’s neutral.
