Comparison Of Formic Acid Together With Acetic Acid

Formic Acid. HCOOH.

Points of Resemblance

1. Forms salts amongst bases, carbonates, together with bicarbonates.
2. Forms esters when treated amongst alcohols inward the presence of conc. H2SO4
3. Reacts amongst PCl5 to laissez passer on formyl chlorine which beingness unstable decomposes to laissez passer on CO+ HCl.
4. Forms an amide (formamide) when its ammonium tabular array salt is heated.

Points of Difference

When formic acid is heated inward a higher house 160C nether pressure, it gives CO2 + H2.

When formic acid is heated amongst conc. H2SO4, it gives CO + H2O

Formic acid does non react amongst Cl2 inward the presence of scarlet P.

Gives formaldehyde when its calcium tabular array salt is heated.

When its sodium tabular array salt is heated amongst soda-lime, hydrogen is formed.

When its sodium tabular array salt is heated to 360C, sodium oxalate is formed.

Electrolysis of aqueous solution of sodium tabular array salt gives hydrogen.

Formic acid reduces Fehling’s solution together with Tollens’ reagent.

Acetic Acid. CH3COOH.

Points of Resemblance

1. Forms salts amongst bases, carbonates, together with bicarbonates.
2. Forms esters when treated amongst alcohols inward the presence of conc. H2SO4.
3. Reacts amongst PCl5 to laissez passer on acetyl chloride.
4. Forms an amide (acetamide) when its ammonium tabular array salt is heated.

Points of Difference

1. Acetic acid is stable to heat.
2. Acetic acid does non react amongst conc. H2SO4.
3. Acetic acid reacts amongst Cl2 inward the presence of P to cast mono-, di-, or trichloroacetic acid.
4. Gives acetone when its calcium tabular array salt is heated.
5. When its sodium tabular array salt is heated amongst soda-lime, methyl hydride is formed.
6. Its sodium tabular array salt is stable at 360C.
7. Electrolysis of aqueous solution of sodium tabular array salt gives ethane.
8. Acetic acid does non react amongst Fehling’s solution or Tollens’reagent.
