Question

question 10 (1 point) using the vsepr theory, predict that the shape of ammonia, nh3. bent linear tetrahedral triangular planar trigonal pyramidal

Explanation:

Step1: Determine central atom

Nitrogen is the central atom in NH₃.

Step2: Calculate electron - pair geometry

N has 5 valence electrons. It forms 3 bonds with H atoms and has 1 lone - pair. So the total number of electron pairs around N is 4 (3 bonding pairs + 1 lone pair). According to VSEPR, 4 electron pairs have a tetrahedral electron - pair geometry.

Step3: Determine molecular shape

The presence of 1 lone - pair distorts the shape. The molecular shape of NH₃ is trigonal pyramidal.

Answer:

trigonal pyramidal
