i think it's C or D.
Explanation:
but if I had to choose i would pick D. sorry if it's wrong. but i hope it's right.
Answer:
Tetrahedral
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.
I think it’s D the melting point everything else doesn’t really make sense
