Question

If true enter 1, else enter 0.
It makes no difference at which vertex, the lone pair in an ${AX}_5$ molecule is located.

• A. 1

Answer 1

The correct option is A 1
It makes no difference at which vertex, the lone pair in an $A{X}_5$ molecule is located.

The central atom A contains 1 lone pair and 5 bond pairs of electrons. This results in $s{p}^3{d}^2$ hybridization with octahedral geometry.
