Answer:
Tetrahedral
Step-by-step explanation:
SF2H2 is a derivative of the sulfuranes (SL4) compounds. The quantum mechanics of these sulfuranes is quite complicated.
Simply, they consist of ten electrons around the sulphur central atom one of which is a lone pair. The electronegativity of fluorine plays a key role in the structure and molecular geometry of SF2H2.
The molecule is found to be tetrahedral in shape by quantum mechanical calculations.
