← ScienceWhich property change occurs when an atom's valence orbital hybridization shifts from sp3 to sp2?
A)Increased bond angles between ligands✓
B)Reduced electronegativity of the atom
C)Enhanced paramagnetism from unpaired electrons
D)Decreased reactivity toward electrophilic attack
💡 Explanation
When orbital hybridization shifts from sp3 to sp2, the geometry around the atom changes because sp2 orbitals arrange in a trigonal planar structure, leading to larger bond angles (~120°) compared to the tetrahedral arrangement of sp3. Therefore, increased bond angles result, rather than electronegativity, paramagnetism, or reactivity shifts which have distinct mechanisms.
