Chemistry Question on Chemical bonding and molecular structure
The molecular shapes of SF4,CF4 and XeF4 are
the same with 2,0 and 1 lone pairs of electrons on the central atoms, respectively.
the same with 1,1 and 1 lone pairs of electrons on the central atoms, respectively.
the same with 0,1 and 2 lone pairs of electrons on the central atoms, respectively.
the same with 1,0 and 2 lone pairs of electrons on the central atoms, respectively.
the same with 1,0 and 2 lone pairs of electrons on the central atoms, respectively.
Solution
The molecular structure of SF4 is square pyramid due to the presence of one lone pair on S atom. CF4 adopts a tetrahedral geometry, and XeF4 has a square planar structure with two lone pairs on the Xe atom.
The correct answer is option (D): the same with 1,0 and 2 lone pairs of electrons on the central atoms, respectively.
