Which mechanism explains increased reactivity when atomic orbitals hybridize?

A)Increased electron density near nucleus
B)Reduced total electron kinetic energy
C)Directional concentration of electron density
D)Decreased electron-electron repulsion overall

💡 Explanation

Hybridization causes higher reactivity because valence electrons concentrate in a specific direction due to directional concentration of electron density. This polarization allows easier bond formation; therefore reactivity improves, rather than reducing energy.
