1. NEET 2026EasyPreparation of Hydrogen
   Q1

   Methane reacts with steam at 1273 K in the presence of nickel catalyst to form:

   • ACO and H₂O
   • BCO₂ and H₂
   • CCO and H₂
   • DCO₂ and H₂O

   Show answer & solution

   Correct answer: (C)

   CH₄ + H₂O → CO + 3H₂ (steam reforming) used for industrial H₂.

   Which of the following statements are NOT correct?
   A. Hydrogen is used to reduce heavy metal oxides to metals.
   B. Heavy water is used to study reaction mechanism.
   C. Hydrogen is used to make saturated fats from oils.
   $D$. The $H-H$ bond dissociation enthalpy is lowest as compared to a single bond between two atoms of any elements.
   E. Hydrogen reduces oxides of metals that are more active than iron.
   
   Choose the most appropriate answer from the options given below: [NEET 2023]

   • AB, D only
   • BD, E only
   • CA, B, C only
   • DB, C, D, E only

   Show answer & solution

   Correct answer: (B)

   Statement A, B, C are correct
   (D) $H-H$ bond dissociation energy is maximum as compared to single bond between two atom of any element.
   (E) Hydrogen reduces oxides of metal that are less active than iron.
3. NEET 2022EasyUses of Hydrogen
   Q3

   The element used for welding metals with high melting points is: [NEET Re-2022]

   • AHe
   • B${Cl}_2$
   • C$H_2$
   • DNe

   Show answer & solution

   Correct answer: (C)

   The oxy-hydrogen flame can produce the temperature of 4000 K . So atomic hydrogen is used for welding of metals with high melting point.
