Why pKa of propiolic acid is significantly lower than the pKa of propanoic acid?
Wiki User
∙ 11y ago
due to propiolic acid having more s character than propanoic acid (sp hybridisation in the triple bond), it tends to be more electronegative than propanoic acid and therefore weakens the O-H bond allowing the H+ to dissociate easier, making it a stronger acid than propanoic acid

The presence of the triple bond in propiolic acid leads to greater acidity compared to propanoic acid. The triple bond is more electron-withdrawing than the double bond in propanoic acid, making the hydrogen ion more easily dissociable and lowering the pKa value.

What is the common name of propanoic acid?
The common name of propanoic acid is propionic acid.
Which is more acidic methanesulfonic acid or propanoic acid?
Methanesulfonic acid is more acidic than propanoic acid. This is because the sulfonic acid group in methanesulfonic acid is a stronger acid group compared to the carboxylic acid group in propanoic acid.
Why melting point of ethanoic acid is higher than propanoic acid?
Ethanoic acid is more polar than propanoic acid, as it contains fewer carbon-carbon and carbon-hydrogen bonds.
What is the pH of 1M propanoic acid?
- log(1 M propanoic acid) = 0 pH ========( remember, acids may register below scale )
What reactant is needed to combine pentanol to produce pentyl propanoate?
The reactant needed to combine pentanol to produce pentyl propanoate is propanoic acid. Pentanol and propanoic acid react in the presence of an acid catalyst, such as sulfuric acid, to form water and pentyl propanoate.
What is the common name of propanoic acid?
The common name of propanoic acid is propionic acid.
Which is more acidic methanesulfonic acid or propanoic acid?
Methanesulfonic acid is more acidic than propanoic acid. This is because the sulfonic acid group in methanesulfonic acid is a stronger acid group compared to the carboxylic acid group in propanoic acid.
What is the dissociation of propanoic acid (CH3CH2CO2H) in water?
It is a weak acid, as it does not dissociate completely.
What is the molecular mass of propanoic acid?
The molecular mass of propanoic acid, also known as propionic acid, is approximately 74.08 g/mol.
Is c4h8o2 propanoic acid?
No, C3H7COOH is butanoic acid (butyric acid) or propanecarboxylic acid
What type of fatty acid is a propanoic acid?
Propionic acis is not a fatty acid.
Why melting point of ethanoic acid is higher than propanoic acid?
Ethanoic acid is more polar than propanoic acid, as it contains fewer carbon-carbon and carbon-hydrogen bonds.
How many oxygens are in propanoic acid?
2

What is the molar mass of 1-propanoic acid?
The molar mass of 1-propanoic acid (also known as propionic acid) is approximately 74.08 g/mol.
What is the pH of 0.1 M propanoic acid?
The pH of a 0.1 M propanoic acid solution can be calculated using the dissociation constant (Ka) of propanoic acid, which is 1.3 x 10^-5. First, calculate the concentration of propanoate ions by solving for x in the equilibrium expression for propanoic acid. Then, calculate the pH using the formula pH = -log[H+], where [H+] is the concentration of protons in the solution.
