CARBOXYLIC ACIDS
INTRODUCTION
(a) Organic compounds in which – COOH group is present are called as ‘Carboxylic Acid’.
(b) These compounds are also called fatty acids because their higher members like Palmitic acid or
stearic acid were usually obtained from animal fats.
(c) The term ‘Carboxylic’ was firstly proposed by scientist ‘Bayer’.
(d) Their general formula is
CnH2nO2 or CnH2n+1–COOH
(e) Hybridisation state of carboxylic carbon is sp2.
(f) In carboxylic acids, both oxygen-carbon bond lengths are equal due to resonance. It is 1.28 Aº.
(g) On the basis of number of –COOH group, they are called mono, di or tri carboxylic acid.
(h) Acids shows chain and functional isomerism. They shows functional isomerism with ester.

PHYSICAL PROPERT IES
(a) Carboxylic acids are colourless with specific smell liquid. They are in liquid state upto 9 carbon
and above 9 carbon they are solids.
(b) Lower carboxylic acids are soluble in water. It is due to H–bonding. Higher carboxylic acids are
insoluble in water due to increase in covalent character.
(c) Their melting point and boiling point  molecular mass.

1
No. of branches
(d) Boiling point of acids are comparatively higher than equivalent esters due to H – bonding. For
example, methyl formate (HCOOCH3) has a boiling point 57ºC whereas acetic acid has a boiling
point 118ºC.
(e) Formic acid is used in leather industries, also known as corrosive.
(f) 8 – 10% acetic acid is called
‘Vinegar’.
(g) At 16–20ºC pure acetic acid converts into ice like solid called glacial acetic acid.
(h) In industries, acetic acid is prepared by oxidation of ethanol and oxidation occurs by aceto bacter
aceti or micoderma aceti bacterias. The process is called quick vinegar process.
(i) Boiling point of formic acid is 100.5ºC while acetic acid has 118ºC. For removal of water from formic
acid we can use reagent PbCO3 (lead carbonate) and H2S.

Passage based Questions
Passage-1 (Q. 7 to 9)
Carboxylic acids having at least one -hydrogen react with Cl2 or Br2 in the presence of phosphorus (or a
phosphorus halide) to give -halo acids. This reaction is known as Hell-Volhard-Zelinsky reaction (HVZ
reaction),

The HVZ reaction is limited to the formation of -chloro and -bromo acids and it is sometimes awkward to
carry out. The reagents (X2 and P) are noxious and the reaction time is often long and the conditions of
reaction are harsh.
