← ScienceWhich outcome occurs when a silica catalyst's Lewis acidic sites insufficiently hybridize?
A)Reduced Brønsted acid site formation✓
B)Selective hydrogenation reaction blockage
C)Increased surface area hydrophobicity
D)Enhanced electron delocalization stabilization
💡 Explanation
Reduced Brønsted acidity results when insufficient hybridization prevents sufficient electron density shift; this *orbital hybridization* alters surface proton affinity because these sites become less able to donate protons, therefore catalyst activity decreases rather than allowing alternate surface modifications.
