Answer to Question #113104 in Organic Chemistry for saad

Question

In which structure are three atoms bonded together in a straight line?
A poly(ethene), ]
B propane, C3H8
C silicon tetrachloride, SiCl4
D sulfur hexafluoride, SF6
( ) CH2

Answer 1

/fix/

In A, B and C carbon and silicon atoms have tetraedral surrounding (hybridization sp³), no thirds of atoms, bonded in a line.

In D sulfur hexafluoride has perfect tetragonal bipyramidal structrure (hybridization sp³d²), there opposite fluorine atoms, along with central sulfur atom, are connected in a straight line.
