SO2 has two double bonds and one lone pair of electrons. CO2 is linear while SO2 is bent shaped. Carbon dioxide is linear, while sulphur dioxide is bent (V-shaped). In your answer, use carbon tetrachloride, CCl4, as an example. CO 2 is a AX 2 type molecule in which there are two bonding pairs and no lone pairs on carbon atom due to which it is linear. This indicates that the individual dipole moments are equal in magnitude and pointed in opposite directions and as a result, they cancel out each other.On the other hand, water is a polar molecule having a dipole moment, 1.84D. There is no charge on the molecule because there are no lone electron pairs. Share 4. Question: Explain Why The CO2 Molecule Is Linear Whereas The SO2 Molecule Is Bent. CO 2 molecule has only two bonds which lie farthest to each other to minimise repulsion, making an angle of 180°.. H 2 O, on the other hand, has a lone pair. Explain how a molecule that contains polar bonds can be nonpolar. This is due to the different numbers of electrons in each molecule and VSEPR (Valence Shell Electron Repulsion) theory. (By the way, don't worry about the octet rule as it applies to S in SO2. Explain Why The CO2 Molecule Is Linear Whereas The SO2 Molecule Is Bent. Share with your friends. Since carbon dioxide is linear it has $3n-5 = 4$ vibrations and they are pictured below. The CO2 molecule has a zero dipole moment even though C and O have different electronegativities and each of the C = O bond is polar and has the same dipole moment. In the carbon dioxide, the two double bonds try to get as far apart as possible, and so the molecule is linear. Co2 molecule is linear whereas So2 molecule is bent because ️ because CO2 is a Ax2 type molecule in which there are two bonding and no lone pair on carbon due to which it is linear.. whereas SO2 is a AX2E type molecule with two bonding pairs and 1 lone pairs on sulphur atom. Why is CO2 a linear molecule whereas H2O has a v-shaped geometry? 4. Give Reason. The electron pair geometry is trigonal planar and the molecular geometry is "bent." In sulphur dioxide, as well as the two double bonds, there is also a lone pair on the sulphur. This problem has been solved! The SO2 molecule is a bent molecule, existing as a resonance structure, with a lone pair of electrons on the S. The CO2 has a linear shape, being O=C=O. Explain why sulfur dioxide molecules, SO2, have a bent shape whereas carbon dioxide molecules, CO2, are linear The sulfur atom in SO2 contains three negative charge centers arranged to give a … 1. Explain why the CO2 molecule is linear whereas the SO2 molecule is bent. Polarity in a molecule occurs due to the unequal sharing The asymmetric stretch does result in a change in dipole moment so it is ir-active. There are two electron domains around the central carbon atom, therefore it is linear (Niles, 2004). SO2 and CO2..... CO2 has two double bonds and no lone pairs, and is therefore, linear: O=C=O. The geometry of C O 2 is linear (electrons geometry is linear too) because the two bonds are the farthest apart and the bond angle is 1 8 0 o.This is what makes of C O 2 a non polar molecules because the dipole moment of both bonds cancel out. The symmetric stretch does not result in a change (of the initially zero dipole moment), so it is ir-inactive. Carbon dioxide (CO2) is nonpolar because it has a linear, symmetrical structure, with 2 oxygen atoms of equal electronegativity pulling the electron density from carbon at an angle of 180 degrees from either direction. As lone pair- bond pair repulsion is greater than bond pairbond pair repulsion, the repulsions due to the lone pair decreases the angle between the two bonds, giving the molecule a bent shape. 3. This theory states that as electrons are negatively charged, the valence electrons in different atoms in a molecule repel each other.
