Question

A compound with a cyclopentadiene ring fused to a cyclohexanone ring is treated with conc. H2SO4 and heat to give X. X then reacts with Z-substituted benzenediazonium ion (Z-C6H4-N2+) in OH- medium to give Y (Major product), an orange red colour dye. Choose the correct statements regarding the above reaction/products.
(A) In basic medium compound X forms 9 cannonical structure.
(B) If Z-group is electron donating rate of reaction from X to Y increases.

Prashant Kotian · Accepted Answer

Correct answer: A,D. X  OH OH  O   9 canonical structure are possible Y  N N Z OH Electron withdrawing group in diazonium salt increases the rate of coupling reaction. SECTION – B
