Worked practice questions

Which of the following arrangements is in correct order of increasing electronegativity (Pauling scale)?

  1. F < O < N < C
  2. N < C < O < F
  3. C < N < O < F
  4. O < F < N < C
Show answer and solution

Correct answer: C. C < N < O < F

Electronegativity increases across a period and decreases down a group. The Pauling-scale values for period 2 nonmetals: - C: 2.55 - N: 3.04 - O: 3.44 - F: 3.98 (highest of any element) So the correct ascending order is **C < N < O < F**. Option A reverses everything. Option C breaks the trend by putting F before O. Memory aid: "FONClBrISCHP" is the electronegativity ladder from highest to lowest among common nonmetals (F first, P last among this set).

As per your syllabus, the IUPAC OFFICIAL name + symbol for Z = 104 is which?

  1. Kurchatovium, Ku
  2. Dubnium, Db
  3. Rutherfordium, Rf
  4. Seaborgium, Sg
Show answer and solution

Correct answer: C. Rutherfordium, Rf

As per your syllabus, Z=104 is Rutherfordium (Rf). Kurchatovium was the Soviet rival name. 105 = Db, 106 = Sg.

As per your syllabus, predicting the formula formed by SILICON (Group 14) and BROMINE (Group 17) gives which compound?

  1. SiBr₄
  2. Si₂Br
  3. SiBr₂
  4. SiBr
Show answer and solution

Correct answer: A. SiBr₄

As per your syllabus, Si valence = 4, Br valence = 1 ⇒ SiBr₄.
