Question

Which of the following molecule does not have a linear arrangement of atoms? 

(a) H₂S 

(b) C₂H₂ 

(c) Be₂ 

(d) CO₂

Answer 1

The correct option is : (a) H₂S 

Explanation:

For linear arrangement of atoms the hybridisation is sp. (bond angle = 180°). 

Only H₂S has sp³-hybridisation and hence it has angular shape while C₂H₂, BeH₂ and CO₂ all involve sp-hybridisation and hence has linear arrangement of atoms.
