JEE Chemistry 2025 Question with Solution

Given: Match the groups in LIST-I with the element symbols in LIST-II.

Find: The correct correspondence and hence the correct option.

Pnicogen belongs to group $15$, and Mc (Moscovium) is the synthetic element of group $15$. So, A-IV.

Chalcogen belongs to group $16$, and Lv (Livermorium) belongs to group $16$. So, B-III.

Halogen belongs to group $17$, and Ts (Tennessine) belongs to group $17$. So, C-I.

Noble gas belongs to group $18$, and Og (Oganesson) belongs to group $18$. So, D-II.

Thus, the correct matching is A-IV, B-III, C-I, D-II.

Therefore, the correct option is B.

Given:

• Pnicogen = group $15$
• Chalcogen = group $16$
• Halogen = group $17$
• Noble gas = group $18$

Find: Which symbols among Ts, Og, Lv, Mc belong to these groups.

From the periodic table:

1. Mc = Moscovium, which is in group $15$.
2. Lv = Livermorium, which is in group $16$.
3. Ts = Tennessine, which is in group $17$.
4. Og = Oganesson, which is in group $18$.

So the matching becomes:

• A $\to$ IV
• B $\to$ III
• C $\to$ I
• D $\to$ II

Hence, the final matching is A-IV, B-III, C-I, D-II, which corresponds to option (2).

Therefore, the correct option is B.
