Identify linear molecule from following.

Options

  1. ASO ₂
  2. BBCl ₃
  3. CCO ₂
  4. DNH ₃

Correct answer

C. CO ₂

Step-by-step solution

For SO ₂ , the central sulphur atom has 2 bond pairs and 1 lone pair. The hybridization is sp^2 and the shape is bent. For BCl ₃ , the central boron atom has 3 bond pairs and 0 lone pairs. The hybridization is sp^2 and the shape is trigonal planar. For CO ₂ , the central carbon atom has 2 bond pairs (sigma bonds) and 0 lone pairs. The hybridization is sp and the shape is linear. For NH ₃ , the central nitrogen atom has 3 bond pairs and 1 lone pair. The hybridization is sp^3 and the shape is trigonal pyramidal. Thus
