Passage
An organic acid A has neutralisation equivalent 148. A on vigorous oxidation with concentrated, alkaline KMnO4 followed by acidic work -up gives another acid whose neutralisation equivalent is 83. A on heating with sodalime produces an organic liquid B. B on vigorous oxidation with concentrated, alkaline KMnO4 solution followed by acid workup gives another different acid of neutralisation equivalent 122. P, an isomer of A, on vigorous oxidation with concentrated, alkaline KMnO4 followed by acidic workup produced yet another different acid Q whose neutralisation equivalent is 70. Also, Q on treatment with CI2/CCI4 in the presence of AICI3 gives a single monochlorination product via aromatic electrophilic substitution reaction.
Q.
The structure of A is
