Question

what is the molecular geometry of sef4?
octahedral
square planar
linear
tetrahedral
square pyramidal
trigonal planar
bent
seesaw
t - shaped
trigonal pyramidal
trigonal bipyramidal

Explanation:

To determine the molecular geometry of \(SeF_4\), we first look at the central atom \(Se\). Selenium has 6 valence electrons. In \(SeF_4\), it forms 4 single bonds with \(F\) atoms (using 4 valence electrons). So, there is \(6 - 4= 2\) non - bonding electrons (1 lone pair).
The electron - pair geometry of \(SeF_4\) (based on \(AX_4E\) notation where \(A\) is the central atom, \(X\) is the bonded atom, and \(E\) is the lone pair) is trigonal bipyramidal (because for \(AX_4E\), the electron - pair geometry is trigonal bipyramidal). But when considering the molecular geometry (ignoring the lone pair in terms of the shape description for the atoms), the molecular geometry is seesaw.

Answer:

Seesaw
