CH_(3)CHO can be prepared by (I) CH_(3)COCl+H_(2) overset(d//BaSO_(4)

1.	CH_(3)CHO can be prepared by (I) CH_(3)COCl+H_(2) overset(d//BaSO_(4))(rarr)CH_(3)CHO+HCl (II)CH_(2)=CH_(2)+O_(2) overset(Pd(II)//Cu(II))underset(I n water)(rarr) CH_(3)CHO which of the above is in accordance with NGT rules?
Answer» only II Only I Both (a) and (B) None of these Solution :METHOD I used `Pd//BaSO_(4)` . `BaSO_(4)`CAUSES toxic problems in water. Hence, this synthesis is not in accordance with `NGT`RULES. Method `II` is desirable.
