In the Rosenmund's reduction, \(BaS{O_4}\) taken with catalyst \(Pd\) acts as
1 Promotor
2 Catalytic poison
3 Cooperator
4 Absorber
Explanation:
In the Rosenmund's reduction, \(BaSO _4\) taken with catalyst Pd acts as Catalytic poison by reducing the activity of palladium due to its low surface area meaning it decreases the reducing power of palladium in order to prevent over-reduction of the acid.

The Clemmenson reduction of acetone yields
1 Ethanol
2 Ethanal
3 Propane
4 Propanol
Explanation:
It's Obvious.

Catalyst \(SnC{l_2}/HCl\) is used in
1 Stephen's reduction
2 Cannizzaro reaction
3 Clemmensen's reduction
4 Rosenmund's reduction
Explanation:
In the Stephen's reduction alkyl cyanide is reduced to aldehyde by \(SnCl _2 / HCl\). \(R - C \equiv N +2 H \stackrel{ SnCl _2 / HCl }{\longrightarrow} \underset{\text { alidine }}{ RCH }=\underset{\text { hydrochloride }}{ NH \cdot HCl } \stackrel{ H _2 O }{\longrightarrow} \underset{\text { aldehyde }}{ RCHO }+ NH _4 Cl\)
