The chemical elements are arranged in the order of increasing electronegativities in the sequenceA. P, Si, Se, Br, NB. Si, Se, P, Br, NC. Si, P, Se, Br, ND. Se, P, Si, Br, N |
|
Answer» Correct Answer - C Electronegativity increases as we move from left to right in a period so phosphours is more electronegative than silicon and bromine is more electronegative than selenium and electronegativity decreases as we descend the group. `therefore` Nitrogen is the most electronegative element of the given elements. `therefore` The observed order is Si, P, Se, Br, N. |
