Question

What is the total no. of bond pairs in xeo3f2?

Answer 1

Hello Dear,

Your answer is here, 

Bond pair is basically known as The electron which are involved in bonding are called bond pair.


So , For XeO₃F₂ , I attached the diagram here, you can see.

3 double bond & 2 single bond  are mentioned there , So the total number of Bond pair are 5. 

Hence,
               The Total number of Bond pair in XeO₃F₂ =  5
                                             &
               The total number of Lone pair = 0

and one more thing:→

The hybridization of XeO₃F₂→→ is sp₃d  and it has 5 substitutes.

I hope it helps.

Have a Marvelous Day.

Answer 2

There is an easy formula/trick for calculating the number of bond pairs and lone pairs in a compound. Since this question is only asking for the number of bond pairs, I will stick to that.

First, we need to identify the central atom. In this case, it is Xenon (Xe). Next, we need to remember that the number of bond pairs is equal to the number of different atoms bonded to the central atom. If there are 3 atoms bonded to the central atom, then the bond pair is 3 and likewise.

In this example, we are given Xe$O_{3}$$F_{2}$. Here, there are 3 oxygen atoms and 2 flourine atoms attached to the central atom which is Xenon. Hence, the number of bond pairs is 5.
