Question

out of H2Se SiO2 H2O CO2 which of these does not arrange itself into tetrahedral environment when bonding ins a solid state?

ok i don't know i need help with this big time

There is electronic geometry as well as molecular geometry. The question doesn't specifiy which and it should. However, the answer PROBABLY is CO2 since that is a linear molecule.
O=C=O or
<b>:O::C::O:</b> and put two more dots above each O.
