MCQ
Which of the following attain the linear structure?
- ABeCl2
- BNCO+
- CNO2
- DCS2
✓
Answer
-
BeCl2
-
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).
