The most reactive among the halogens is:
✓ Correct answer: a) Fluorine
ExplanationFluorine is the most reactive halogen because: Small Atomic Size: Fluorine has the smallest atomic radius among halogens, leading to a strong attraction for electrons.High Electronegativity: It is the most electronegative element in the periodic table, making it highly effective in gaining electrons.Low Bond Dissociation Energy: The F-F bond in molecular fluorine is weak due to electron repulsion between the two small atoms, which makes it highly reactive.Reactivity Trend in Halogens: Fluorine > Chlorine > Bromine > Iodine 342
