explainwhether each of the molecule is polar or not and explain why c2cl2 and scl2
C2Cl2 It is a linear molecule Cl-C=-C-Cl so its dipole moment becomes zero and it behaves as a non polar molecule.
SCl2: S has four orbital shapes, two of which share one electron with Cl ion. but it is not linear, the angle between the the two Cl ions is 103 degrees (tetrahedrial bonds), so the next effect is for the molecule to have a dipole moment and it is polar https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcQDk8FwJAL69uV0NSIOwmTAJKg87o3h-WMa6iW5SJcRwrffVkR8
I believe you must have made a typo. C2Cl2 doesn't exist. Both C atoms as drawn by Cl-C=C-Cl are three valent and that is a no no. You may have meant C2H2Cl2. That doesn't change the answer Bob Pursley gave you.
To determine whether a molecule is polar or not, we need to consider its molecular geometry and the polarity of its bonds.
C2Cl2 (Dichloroethylene):
- Each carbon atom is bonded to two chlorine atoms in a linear arrangement, forming a molecule with a linear geometry.
- Chlorine is more electronegative than carbon, so the carbon-chlorine bonds are polar.
- However, since the molecule is linear and symmetrical, the opposing polar bonds cancel each other out, resulting in a nonpolar molecule.
- Therefore, C2Cl2 is nonpolar.
SCl2 (Sulfur dichloride):
- Sulfur is bonded to two chlorine atoms in a bent or V-shaped molecular arrangement.
- The chlorine atoms are more electronegative than sulfur, causing the S-Cl bonds to be polar.
- The molecule is non-symmetrical, meaning the polar bonds do not cancel each other out.
- Therefore, SCl2 is a polar molecule.
In summary, C2Cl2 is nonpolar because its polar bonds cancel out due to its linear and symmetrical geometry. SCl2 is polar because its polar bonds do not cancel out due to its bent or V-shaped geometry.
To determine whether a molecule is polar or not, we need to analyze its molecular geometry and the distribution of its electrons. A molecule is considered polar if it has an uneven distribution of charge, creating a positive and negative end (poles).
Let's analyze each molecule individually:
1. C2Cl2 (Dichloroethylene):
To determine the polarity of C2Cl2, we need to consider its molecular shape. C2Cl2 consists of two carbon atoms joined by a double bond (C=C), with a chlorine (Cl) atom attached to each carbon.
- The central carbon-carbon double bond is linear.
- Each carbon has two chlorine atoms attached, creating a tetrahedral structure around each carbon.
- Since chlorine is more electronegative than carbon, it pulls the electron density towards itself.
- As a result, the chlorine atoms exert an uneven pull towards themselves, making C2Cl2 a polar molecule.
2. SCl2 (Sulfur Dichloride):
Similar to C2Cl2, we need to analyze the molecular geometry of SCl2.
- SCl2 consists of a central sulfur (S) atom and two chlorine (Cl) atoms attached to it.
- The sulfur atom has two bonding pairs and one lone pair of electrons, creating a bent or V-shaped molecular shape.
- Chlorine is more electronegative than sulfur, causing an uneven distribution of charge.
- The presence of the lone pair of electrons on sulfur further contributes to the polarity of the molecule.
- Due to the bent shape and the distribution of charge, SCl2 is a polar molecule.
In summary, both C2Cl2 (Dichloroethylene) and SCl2 (Sulfur Dichloride) are polar molecules based on their molecular geometries and the electronegativity differences between the atoms involved.
