What is the Lewis structure for HClO4?

Answer 1

"Central Cl atom, single bonded to 4 Oxygen atoms. Each oxygen has a formal charge -1 and 3 lone pairs. Cl has a formal charge of +3. bonded in tehrahedral"

A better structure is central C atom, 3 double bonds to 3 O atoms with two lone pairs each and one single bond to one O atom with three lone pairs. Only the single bonded oxygen has a formal charge of -1, limiting formal change. This still has a tetrahedral shape.

Answer 2

The dot structure for HClO4 begins with a Cl atom in the center doubly bonded on three sides to a single O atom. On the fourth side is a single bond to another O atom. All four O atoms have two pair of double dots. The singly bonded O atom also has a single bond to an H atom.

Answer 3

H-C=O

|

Cl

Three lone pairs (that's 6 electrons) around Cl and two lone pairs (that's 4 electrons) around O

H-Cl=C=O

or it could go

Cl-C=O hydrogen forming single bond of the carbon

H

Answer 4

In the Lewis structure for HClO4, the central atom is Cl surrounded by four O atoms and one H atom. The Cl atom is the central atom, bonded to each of the four O atoms through single bonds and to the H atom through a single bond as well. Each O atom has a lone pair of electrons.

Answer 5

The dot structure for ClO4 starts with a Cl atom in the center with four single bonds, each attached to a single O atom. Each O atom has a pair of dots on their unbonded sides.

Answer 6

Clo4- has a central Cl atom that forms with 4 single O bonds and no double bonds.
