Correct option is B) Electronegativity decreases in a group on going from top to bottom. Therefore increasing electronegativity order is I < Br < Cl < F. WebSep 8, 2024 · The trend in bond energies for the halogens is therefore \[Cl–Cl > Br–Br > F–F > I–I\] Similar effects are also seen for the O–O versus S–S and for N–N versus P–P single bonds. Bonds between hydrogen and atoms in a given column in the periodic table are weaker down the column; bonds between like atoms usually become weaker down ... restorx johns lyng

The ability of an atom in a molecule to attract a shared electron pair to itself, forming a polar covalent bond, is called its electronegativity. The negative side of a polar covalent bond corresponds to the more electronegative element. Furthermore the more polar a bond, the larger the difference in … WebRank the following in order of decreasing leaving group ability, putting the best first.
