which molecule has a trigonal planar shape?\ncarbon monoxide\nboron trichloride\nsilicon tetraiodide\ncarbon tetrafluoride

which molecule has a trigonal planar shape?\ncarbon monoxide\nboron trichloride\nsilicon tetraiodide\ncarbon tetrafluoride

Answer

Brief Explanations:

In boron trichloride ($BCl_3$), the central boron atom has 3 bonding pairs and no lone - pairs. According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, this results in a trigonal planar molecular geometry. Carbon monoxide ($CO$) is linear. Silicon tetraiodide ($SiI_4$) and carbon tetrafluoride ($CF_4$) have tetrahedral geometries due to 4 bonding pairs around the central atom.

Answer:

B. boron trichloride
