In aperiodictable thebasiccharacterof oxides

Answer»

increasesfrom left torightand decreasesfromtop tobottom
decreasesfrom RIGHTTO leftand increasesfromtop tobottom
decreases fromleft TORIGHT andincreasesfromtop tobottom
decreasesfrom leftto RIGHTAND increasesfrombottomto top

Solution :As theionizationenthalpyand electronegativityincrease alonga periodthe basiccharacterof oxidesdecreases.Converselyas theionizationenthalpyand electronegativitydecreasefrom TOPTO bottomin a groupthe basiccharacterof oxidesincreases.Thusoption( c) is correct.
