Using the vsepr model, identify the molecular geometry of nitrogen triiodide, ni3, based on the number of electron domains. linear trigonal planar bent tetrahedral trigonal pyramidal trigonal bipyramidal seesaw t-shaped octahedral square pyramidal square planar

Answer : The molecular geometry of is trigonal pyramidal.

Explanation :

Formula used  :

where,

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

The given molecule is,

Number of bond pair = 3

Number of lone pair = 1

The total number of electron pair are 4 that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral.

But as there are 3 atoms around the central oxygen atom, the fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be trigonal pyramidal.

Hence, the molecular geometry of is trigonal pyramidal.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
