Question

What will be the central atom in $XeO{F}_4$?

• A. Xe
• B. O
• C. F
• D. Both (a) & (b)

Answer 1

The correct option is A

Xe

Lets try to remember what we learnt from the videos (concept)

$\to$ Generally central atom is the atom which is least in number.

Therefore, we can conclude that Flourine is not our central atom.

Now, we are left with Xe and O.

Now, do you remember

$\to$ If there are more than one element which we can take as our central atom, then the one which has more number of valance electrons will be our central atom.

Here,

Xe = 8 valance electrons

O = 6 valance electrons.

Therefore, our central atom will be Xe

Correct option $\to$ (a) Xe
