Question

Sulphur trioxide is dissolved in heavy water to form a compound X. The hybridisation state of sulphur in X is :

• A. $s{p}^2$
• B. $s{p}^3$
• C. $sp$
• D. $ds{p}^2$

Answer 1

Answer: (B)

$s{p}^3$

heavy water is D2O i.e Deutrium oxide isotope of hydrogen not H2O

SO3+D2O→D2SO4SO3+D2O→D2SO4

O
∥∥
OD−S=−S=O

OD
sp3 hybridisation.
