Determine the correct molecular geometry (from left to right about each interior atom in ch3ch2nh2.

Answer : The molecular geometry of interior carbon atom is tetrahedral.

Explanation :

Now we have to determine the hybridization of the given molecule.

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,

In this compound, the interior atom or central atom is carbon and , and 2 hydrogen atoms are neighboring atoms.

Number of bond pairs = 4

Number of lone pairs = 0

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

Hence, the molecular geometry of interior carbon atom is tetrahedral.
