Current Question (ID: 7609)

Question:

$\text{Identify the INCORRECT match.}$

Options:

1. $\text{(b)- (ii)}$
2. $\text{(c)- (iii)}$
3. $\text{(d) -(iv)}$
4. $\text{(a)- (i)}$

Solution:

$\text{HINT: Unununium (III) } \Rightarrow \text{Roentgenium.}$ $\text{Explanation:}$ $\text{The question provides a table matching temporary element names with their official IUPAC names:}$ $\text{a. Unnilunium - (i) Mendelevium}$ $\text{b. Unniltrium - (ii) Lawrecium}$ $\text{c. Unnilhexium - (iii) Seaborgium}$ $\text{d. Unununium - (iv) Darmstadtium}$ $\text{From the hint, we know that Unununium (III) corresponds to Roentgenium, not Darmstadtium.}$ $\text{Therefore, the incorrect match is (d) - (iv), where Unununium is incorrectly matched with Darmstadtium}$ $\text{instead of Roentgenium.}$ $\text{All other matches are correct:}$ $\text{- Unnilunium is correctly matched with Mendelevium}$ $\text{- Unniltrium is correctly matched with Lawrecium}$ $\text{- Unnilhexium is correctly matched with Seaborgium}$
