Question
Transcribed Image Text:**Select the Polar Molecule(s)**
The image shows three Lewis structures depicting different organic molecules. Each structure displays atoms with their chemical bonds, showing connectivity and electron pairs. Below is a detailed explanation of each structure:
1. **First Structure:**
- **Atoms:** There is a central carbon (C) atom bonded to three hydrogen (H) atoms and one fluorine (F) atom.
- **Fluorine (F):** It is depicted with three pairs of lone electrons.
- **Polarity Indicator:** The presence of fluorine, a highly electronegative atom, suggests this molecule might be polar due to the electronegativity difference.
2. **Second Structure:**
- **Atoms:** A central carbon (C) atom is bonded to two hydrogen (H) atoms, one carbon (C) atom, and one oxygen (O) atom.
- **Oxygen (O):** It is depicted with two pairs of lone electrons.
- **Polarity Indicator:** The oxygen atom contributes to polarity due to its electronegativity.
3. **Third Structure:**
- **Atoms:** A central carbon (C) atom bonded to four hydrogen (H) atoms.
- **Symmetry Indicator:** The symmetry and uniformity of identical atoms suggest this molecule is non-polar.
**Reset Button:** Available at the bottom to clear selections.
To determine polarity, look for molecules with atoms such as F or O, which create dipoles due to differences in electronegativity.
**Navigation:** Options to navigate between pages, "Prev" for previous and "Next" for the next set of structures, with current status displayed (page 2 of 8).
Expert Solution
Step 1
Polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.
So in other words we can say , a molecule will be considered as polar when there is a large electronegativity difference between two bonded atoms.
