Identify the compounds (A) and (B).
`(A)underset("Iodoform test")underset("Gives(+ve)")((C_(11)H_(12)O)) overset(O_(3)//Red)rarr (B) underset("iodoform test")underset("Gives(+ve)")((C_(10)H_(10)O_(2))) +CH_(2)=O`
(B) is symmetrical p-subsituted compound. (Ignore ozonolysis of benzene ring at the initial stage).

Text Solution

Verified by Experts

i. D.U. in A `= ((2n_(C)+2)-n_(H))/(2)=(24-12)/(2)=6^(@)`.
ii. (A) and (B) both should have (MeCO) group, since they give Iodoform test.
iii. Ozonolysis of (A) gives `CH_(2)=O`, so (A) must have `(-underset(Me)underset(|)C=CH_(2))` group and `(MeCO)` group at p-position. Since the ozonolysis of
group would give `(-underset(Me)underset(|)C=O)` gorup and `CH_(2)=O`. Morever, (B) is a symmetrical p-substitude compoud.
Therefore, the structure of (A) and (B) are:
