Question

which molecule has an octahedral geometry due to sp³d² hybridization?
a. methane (ch₄)
b. acetylene (c₂h₂)
c. sulfur hexafluoride (sf₆)
d. ethene (c₂h₄)

Explanation:

Methane ($CH_4$) has $sp^3$ hybridization and tetrahedral geometry. Acetylene ($C_2H_2$) has $sp$ hybridization and linear geometry. Ethene ($C_2H_4$) has $sp^2$ hybridization and planar - triangular geometry around each carbon. Sulfur hexafluoride ($SF_6$) has $sp^3d^2$ hybridization and octahedral geometry.

Answer:

C. Sulfur hexafluoride ($SF_6$)
