QNEET-2023-Ch-205: NEET 2023 Chemistry - Class 11 NEET-2023-Ch-205 Solution: Which of the following statements are NOT correct? A. Hydrogen…
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 element. E. Hydrogen reduces oxides of metals that are more active than iron. Choose the most appropriate answer from the options given below
Multiple Choice Options
- A B, D only
- B D, E only
- C A, B, C only
- D B, C, D, E only
Step-by-Step Verified Solution
(D, E) explanation
(D) H _ H bond strength/ bond dissociation energy/bond energy of H 2 can not be lowest because bond formed between hydrogen atoms is due to overlapping of 1 s - 1 s .
(E) Hydrogen can not reduces oxides of highly reactive metal.
