Question

CH3CHO can be prepared by CH3COCl + H2 xrightarrowPd/BaSO4 CH3CHO + HCl CH2 = CH2 +O2 xrightarrow[In water]Pd(II)/Cu(II) CH3CHO Which of the above is in accordance with NGT rules? (A) Only II (B) Only I (C) Both (a) and (b) (D) None of these

Method I uses Pd/BaSO4 . BaSO4 causes toxic problems in water. Hence, this synthesis is not in accordance with NGT rules. Method II is desirable

Q. $C H_{3} C H O$ can be prepared by
$C H_{3} COCl + H_{2} P d / B a S O_{4} C H_{3} C H O + H Cl$
$C H_{2} = C H_{2} + O_{2} P d (II) / C u (II) I n w a t er C H_{3} C H O$
Which of the above is in accordance with NGT rules?

Only II

Only I

Both (a) and (b)

None of these

Method I uses $P d / B a S O_{4} . B a S O_{4}$ causes toxic problems in water. Hence, this synthesis is not in accordance with $NGT$ rules. Method II is desirable
