Question

XeF4, SF4 and SiF4 are three molecules given . Which among them has tetrahedral structure?
Justify your answer

Answer 1

SiF4 has a tetrahedral structure.
there is no lone pair bond angle is 108 deg 28'
in xef4 there are 2 lone pairs while in sf4 there is one lone pair

Answer 2

Among the given molecules $SiF_4$ has tetrahedral structure.

Explanation

• The structure of the molecules is drawn based on the number of bonding pairs of electrons and a lone pair of electrons.
• When the molecules such as $XeF_4, SF_4 and SiF_4$ are considered, each has different shapes.

Structure of $XeF_4$

• It has 4 bonding pairs and 2 lone pairs of an electron.
• Due to such arrangement, it has a square planar shape.

Structure of $SF_4$

• It has 4 bonding pairs and 1 lone pair of electron.
• It has a seesaw shape.

Structure of $SiF_4$

• It contains 4 bonding pairs. The lone pair of electrons are absent in this molecules.
• Due to such composition, it has a tetrahedral structure.
