Q
Q: In which of the following compounds does hydrogen exhibit an oxidation state of -1?
Solution:
In NaH (sodium hydride), hydrogen has an oxidation state of -1.
Steps: 6
Show Steps
Step 1: Understand what oxidation state means. It is the charge of an atom in a compound.
Step 2: Know that hydrogen usually has an oxidation state of +1, but it can be -1 in certain compounds.
Step 3: Identify the compounds given in the question. We are looking for where hydrogen is -1.
Step 4: Look at NaH (sodium hydride). Sodium (Na) has an oxidation state of +1.
Step 5: Since the compound is neutral, the total oxidation states must equal 0. Therefore, hydrogen must be -1 to balance the +1 from sodium.
Step 6: Conclude that in NaH, hydrogen exhibits an oxidation state of -1.
