A compound which is most ionic in nature KCl KF NaCl RbF

Which of the following solid does not contain covalent bond Copper Diamond Ice Graphite

Covalent compounds are Directional and rigid Non-directional and non-rigid Non-directional and rigid Directional and non-rigid

Formation of MgO is an example of Ionic bond Non-polar Covalent bond Polar covalent bond Double Covalent bond

CO2 is a nonpolar molecule (μ = 0) whereas SO2 is polar (μ=1.62D). This difference is due to the fact that The C-O bond is nonpolar while the S-O bond is polar C and O are in different groups whereas S and O are in the same group CO2 has an even number of double bonds whereas SO2 has an odd number of double bonds CO2 has an even number of double bonds whereas SO2 has an odd number of double bonds
