Concept explainers
(a)
Interpretation:
The following ball- and -stick model of 3-methyl-2-hexenoic acid should be converted into a Lewis structure.
Concept introduction:
- Lewis structures are the diagrams that show the bonding between the atoms of the molecules and existing lone pairs of electrons.
- Bonding electrons are those electrons which are shared between the atoms resulting in the formation of bond.
- Non-bonding electrons are the valence electrons of the atom which are not shared with another atom.
(b)
Interpretation:
The shape around each carbon atom should be determined.
Concept introduction:
The model which is used in chemistry to determine the geometry of individual molecules with the help of the number of electron pairs surrounded by central atoms is known as Valence shell electron pair repulsion (VSEPR) theory.
(c)
Interpretation:
The polar bonds present in 3-methyl-2-hexenoic acid should be labeled.
Concept introduction:
A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative.

- How do you know when to draw a solid wedge vs a dashed wedge when drawing 3D bond-line structures? I know that solid-wedge means the atom is pointing towards you and dashed wedge means it's in the back, but how do you know which atoms are in the front as opposed to the back? How can you tell what the configuration will look like in space just by looking at the lewis structure or name?arrow_forwardDraw a Lewis structure for the given skeletal molecule.

- Predicting whether molecules are polar or onpo Decide whether each molecule or polyatomic ion is polar or nonpolar. If the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. For example, if the molecule were HCl and you decided the hydrogen atom was closest to the negative side of the molecule, vou'd enter "H" in the last column of the table. atom closest to polar or nonpolar? molecule or polyatomic ion negative side O polar HCN O nonpolar O polar SIF, nonpolar polar HCL O nonpolar Explanation Check © 2021 McGraw-Hill Education.

- Which of the following statements could be true regarding polar molecules?Choose one or more: A polar molecule will not contain polar bonds. A polar molecule may have one or more lone pairs. A polar molecule has an uneven distribution of electron density. A polar molecule will never contain nonpolar bonds. The bond dipoles in a polar molecule will cancel.arrow_forwardConvert the 3-D model of oxalic acid into a Lewis structure and include all nonbonded electron pairs on atoms that contain them. Oxalic acid occurs naturally in spinach and rhubarb. Although oxalic acid is toxic, you would have to eat about nine pounds of spinach at one time to ingest a fatal dose.arrow_forwardIdentify any polar covalent bonds by drawing dipole arrows in the appropriate locations.arrow_forward
