Q. $CH_3CHO$ can be prepared by
$CH_3COCl + H_2 \xrightarrow{Pd/BaSO_4} CH_3CHO + HCl$
$CH_2 = CH_2 +O_2 \xrightarrow[{In\,water}]{Pd(II)/Cu(II)} CH_3CHO$
Which of the above is in accordance with NGT rules?

Environmental Chemistry

Solution:

Method I uses $Pd/BaSO_4 . BaSO_4$ causes toxic problems in water. Hence, this synthesis is not in accordance with $NGT$ rules. Method II is desirable
