Which of the following species has polar and non-polar bonds but molecule as a whole is non-polar?
Options
- AS 2 O 3 2 -
- B( S C N ) 2
- CB e 2 C l 4
- DS i 2 H 6
Correct answer
D. S i 2 H 6
Step-by-step solution
In S i 2 H 6 both polar ( S - H ) and non-polar Si − Si bonds are present but it is non-polar as resultant dipole moment is zero.
