PASSAGE-2
A carbonyl compound P,  which gives positive iodoform test, undergoes reaction with MeMgBr followed by dehydration to give an olefin Q. Ozonolysis of Q leads to a dicarbonyl compound R, which undergoes intramolecular aldol reaction to give predominantly S.
Q. The structure of the carbonyl compound P is
  • a)
  • b)
  • c)
  • d)
Correct answer is option 'B'. Can you explain this answer?

Iodoform test of compound P points out that P has – COCH3 group which shows that it may be either option (a) or (b) of Q. 16. Further since the dicarbonyl compound R has at least one a-H atom w.r.t to one of the carbonyl groups which is possible when R is produced from (b) of Q. 18; (a) option of Q. 16 will give dicarbonyl compound having two –CHO, none of which has a-H atom.



* Structure of R would be R' when P is (A)
