Question

the indicated atom has 3 bonding and 1 lone pair domain. what is the vsepr geometry of the indicated atom? trigonal planar linear tetrahedral trigonal pyramidal

Explanation:

Step1: Determine the electron - domain geometry

The atom has \(3\) bonding domains and \(1\) lone - pair domain, so the total number of electron domains is \(3 + 1=4\). According to VSEPR theory, when the number of electron domains is \(4\), the electron - domain geometry is tetrahedral.

Step2: Determine the molecular geometry

Since there is \(1\) lone pair, the molecular geometry (VSEPR geometry) is trigonal pyramidal. The lone pair repels the bonding pairs more strongly, causing the deviation from the tetrahedral electron - domain geometry.

Answer:

trigonal pyramidal
