Identify the incorrect match.

Name IUPAC Official Name
(a) Unnilunium (i) Mendelevium
(b) Unniltrium (ii) Lawrencium
(c) Unnilhexium (iii) Seaborgium
(d) Unununium (iv) Darmstadtium

Options

  1. A(b), (ii)
  2. B(c), (iii)
  3. C(d), (iv)
  4. D(a), (i)

Correct answer

C. (d), (iv)

Step-by-step solution

(a) The official name of Unnilunium is Mendelevium (Md,Z=101Md, Z = 101).
(b) The official name of Unniltrium is Lawrencium (Lr,Z=103Lr, Z = 103).
(c) The official name of Unnilhexium is Seaborgium (Sg,Z=106Sg, Z = 106).
(d) The official name of Unununium is Roentgenium (Rg,Z=111Rg, Z = 111).

Unununium (Z=111)( Z = 111 ) it is Roentgenium (Rg)( Rg ) not darmstadtium.
