Questions: Question 6 A central atom has one single bond, one double bond, and two lone pair electrons. What is the molecular geometry for this atom? Bent Tetrahedral Trigonal pyramidal Linear

Solution Steps

The steric number is the sum of the number of atoms bonded to the central atom and the number of lone pairs on the central atom. In this case, the central atom has:

• One single bond
• One double bond
• Two lone pairs

Thus, the steric number is: \[ \text{Steric number} = 1 + 1 + 2 = 4 \]

A steric number of 4 corresponds to a tetrahedral electron geometry.

With a tetrahedral electron geometry and two lone pairs, the molecular geometry is "bent."
