MCQ
Which of the following attain the linear structure?
  • A
    BeCl2
  • B
    NCO+
  • C
    NO2
  • D
    CS2
✓

Answer

  1. BeCl2​​​​​​

  1. CS2

Explanation:

BeCl2 (Cl – Be – Cl) and CS2 (S = C = S) both are linear, NCO+ is non-linear. However, remember that NCO(N = C = O) is linear because it is isoelectronic with CO2.

NO2 is angular with bond angled 132º and each O–N bond length of 1.20Ao (intermediate between single and double bond).
