Detailed explanation-1: -Bromine is more electronegative than carbon and so the bond is polarised in the way that we have already described with C-F and C-Cl.
Detailed explanation-2: -Since bromine is to the right of arsenic, bromine has a greater electronegativity than arsenic.
Detailed explanation-3: -Answer and Explanation: The atom with the greatest electronegativity is b. F. The element with the greatest electronegativity is F.
Detailed explanation-4: -Detailed Solution The correct answer is option 1, i.e. Fluorine. Fluorine is the most electronegative element. As we move right in a period, the electronegativity keeps increasing up to the halogens.
Detailed explanation-5: -Electronegativity decreases in a group on going from top to bottom. Therefore increasing electronegativity order is I < Br < Cl < F.
