Identify the incorrect match.
Name – IUPAC Official Name
(a) Unnilunium – (i) Mendelevium
(b) Unniltrium – (ii) Lawrencium
(c) Unnilhexium – (iii) Seaborgium
(d) Unununnium – (iv) Darmstadtium

B
(c), (iii)
C
(d), (iv)
D
(a), (i)
Detailed Solution
Unununnium corresponds to atomic number 111, whose IUPAC official name is Roentgenium (not Darmstadtium, which is element 110).
So (d)–(iv) is the incorrect match. (Unnilunium = 101 Mendelevium, Unniltrium = 103 Lawrencium, Unnilhexium = 106 Seaborgium are correct.)
