Interpretation:
The trigonal planar molecular shape needs to be identified.
Concept introduction:
The molecular shape of the molecule depends on the number of bonds and the lone pair of electrons present in the molecule. The total number of valence electrons decides the hybridization of the central atom thus, the molecular geometry. The number of lone pairs decides the molecular shape which is different from molecular geometry due to lone pair-bond pair repulsion.

Answer to Problem 15STP
Correct Answer: Option B.
Explanation of Solution
Reason for correct option:
The given molecule B has 3 bond pairs of electrons. The central atom will be sp2 hybridized. Thus, the molecular geometry will be trigonal planar. Due to the absence of a lone pair of electrons, the molecular shape will be trigonal planar.
Reason for incorrect option:
The given molecule A has 2 lone pairs of electrons and 2 bond pairs of electrons. Thus, the total number of pairs of valence electrons will be 4. The molecule will be sp3 hybridized. The molecular geometry will be tetrahedral. Due to the presence of 2 lone pairs of electrons, the molecular shape will be bent.
The given molecule C has 4 bond pairs of electrons. The molecule will be sp3 hybridized. The molecular geometry will be tetrahedral. Due to no lone pair of electrons, the molecular shape will also be tetrahedral.
The given molecule D has 2 bond pairs of electrons. The molecule will be sp hybridized. The molecular geometry will be linear. Due to the zero lone pair of electrons, the molecular shape will also be linear.
The given molecule E has 3 bond pairs of electrons and 1 lone pair of electron. The molecule will be sp3 hybridized. The molecular geometry is tetrahedral. Due to the presence of 1 lone pair of the electron, the molecular shape is trigonal pyramidal.

Thanks in advance!arrow_forwardA small artisanal cheesemaker is testing the acidity of their milk before it coagulates. During fermentation, bacteria produce lactic acid (K₁ = 1.4 x 104), a weak acid that helps to curdle the milk and develop flavor. The cheesemaker has measured that the developing mixture contains lactic acid at an initial concentration of 0.025 M. Your task is to calculate the pH of this mixture and determine whether it meets the required acidity for proper cheese development. To achieve the best flavor, texture and reduce/control microbial growth, the pH range needs to be between pH 4.6 and 5.0. Assumptions: Lactic acid is a monoprotic acid H H :0:0: H-C-C H :0: O-H Figure 1: Lewis Structure for Lactic Acid For simplicity, you can use the generic formula HA to represent the acid You can assume lactic acid dissociation is in water as milk is mostly water. Temperature is 25°C 1. Write the K, expression for the dissociation of lactic acid in the space provided. Do not forget to include state symbols.…arrow_forward
