Using the vsepr model, the electron-domain geometry of the central atom in sf2 is using the vsepr model, the electron-domain geometry of the central atom in sf2 is trigonal bipyramidal octahedral tetrahedral trigonal planar linear

Answer : The correct answer is, Tetrahedral.

Explanation :

VSEPR Theory : It predict the geometry of the molecule from the number of electrons pair that surround the central atom.

Formula used :

Number of electrons =

where,

V = number of valence electrons present in central atom

N = number of neighboring atoms

C = charge of cation

A = charge of anion

In the given molecule, S is the central atom and F is the neighboring atom.

Sulfur has 6 valence electrons.

Number of electrons =

The number of electrons is 4 that means the hybridization will be and the electron domain geometry will be tetrahedral.

The electron domain geometry is shown below.

c. 75.7

i think that is the right

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
