Match List I with List II:
| List I | List II |
| i. Ions having positive charge | a. -1 |
| ii. The sum of oxidation number of all atoms in a neutral molecule | b. +1 |
| iii. Oxidation number of hydrogen ion \((H^+)\) | c. 0 |
| iv. Oxidation number of fluorine in \(NaF\) | d. Cation |
| v. Ions having negative charge | e. Anion |
Choose the correct answer from the option given below:
Answer & explanation
Correct answer: option 3
The correct answer is option 3. i-d, ii-c, iii-b, iv-a, v-e.
Let us match each item in List I with the appropriate item from List II based on the given descriptions.
i. Ions having positive charge: These are called cations. Correct match: d (Cation)
ii. The sum of oxidation number of all atoms in a neutral molecule: The sum of oxidation numbers in a neutral molecule is zero. Correct match: c (0)
iii. Oxidation number of hydrogen ion (\(H^+\)): The oxidation number of a hydrogen ion (\(H^+\)) is +1. Correct match: b (+1)
iv. Oxidation number of fluorine in \(NaF\): The oxidation number of fluorine in compounds is always -1. Correct match: a (-1)
v. Ions having negative charge: These are called anions. Correct match: e (Anion)
Summary of matches:
i. Ions having positive charge → d. Cation
ii. The sum of oxidation number of all atoms in a neutral molecule → c. 0
iii. Oxidation number of hydrogen ion (\(H^+\)) → b. +1
iv. Oxidation number of fluorine in \(NaF\) → a. -1
v. Ions having negative charge → e. Anion
The correct answer is: Option 3: i-d, ii-c, iii-b, iv-a, v-e.
