Question

Which of the following is/are INCORRECT order of bond angle?
NF3 > NH3
OF2> OH2
ws
OCH4 = CF4
BF3 = BC13​

Answer 1

Answer:

lp−lp>l

p

−bp>bp−bp

Due to Dp−lp repulsion in PF

3

,F−P−F cmgle will be less than that of BF

3

∴BF

3

<PF

3

BF

3

>NH

3

, as the geometry of BF

3

is triagonal planar while that NH

3

is tetrahedral

As the Fluorine atom pulls the lone pair of electron on P atom, lp−bp repulsion is more pre dominant. Thus NH

3

>PF

3

thus, BF

3

>NH

3

>PF

3

I

3

−

ion linear. This bond angle is 180

o

.

∴ is I

3

−

>BF

3

>NH

3

>PF

3

Answer 2

Answer:

NF3 > NH3

OCH4 = CF4

above order of bond angle are incorrect.
