Vedclass · Answer

(C) Statement $1$ is correct: Atomic hydrogen is produced by passing $H_2$ gas through an electric arc at high temperature.Statement $2$ is correct: Hydrogen gas is not a strong enough reducing agent to reduce $Al_2O_3$ to $Al$.Statement $3$ is correct: Finely divided palladium (or platinum) can adsorb a large volume of $H_2$ gas,a property known as occlusion.Statement $4$ is incorrect: The reaction $C_2H_5OH + Na 	o C_2H_5ONa + \frac{1}{2} H_2$ produces molecular hydrogen,not nascent hydrogen. Nascent hydrogen is typically generated in situ during chemical reactions (e.g.,$Zn + HCl$).Therefore,statements $1, 2,$ and $3$ are correct.
