MCQ
Carbon suboxide ${C_3}{O_2}$ has
  • Linear structure
  • B
    Bent structure
  • C
    Trigonal planar structure
  • D
    Distorted tetrahedral structure

Answer

Correct option: A.
Linear structure
a
(a) Carbon suboxide has linear structure with $C - C$ bond length equal to $130\;\mathop A\limits^o $ and $C - O$ bond length equal to $120\;\mathop A\limits^o $.

$O = C = C = C = O \leftrightarrow {O^ - } - C \equiv C - C \equiv {O^ + }$
