Question

The structure of SF6 is octahedral. What is the structure of SF4 [including the lone pairs if any] ?


(1) trigonal bipyramidal

(2) pyramidal

(3) square planar

(4) trigonal planar

Answer 1

Answer:

c

Explanation:

hii i have sreach in net so it is the true answerr

Answer 2

ANSWER :- Option (1)

EXPLANATION :-

》Sulfur tetrafloride has 5 regions of Electron density around the central sulfur atom.

$\rightarrow$ No of bond pairs = 4 .

$\rightarrow$ No of lone pairs = 1c.

》 These are arranged in Trigonal bipyramidal shape .

》Its molecular geometry is seesaw.

》 Bond angles - 102° F-S- F Between equatorial fluorine atom and 173° Between axial fluorine atoms .

》Nature of molecule - Polar.
