Q

He actual ozone is described as being a

A

Hybrid of the two resonance structure

1
Q

There are two ways in which ozone can be represented by dot diagrams

A

These are both resonance structure

One structure would be insufficient in explaining the structure of ozone

2
Q

The bond lengths are known as intermediate which is

A

Between a normal bond and a double bond

3
Q

If all electrons are landing pairs hey will take up these arrangements

A
Electron pairs = arrangement 
2 = linear 
3 = trigonal 
4= tetrahedral 
5 = trigonal bipyramidal 
6 = octahedral
4
Q

If we have four electron pairs ( 3 bond and one lone pair)

A

Ammonia

Lone pair at the too squeezes the normal pairs together to give true tetrahedron

5
Q

Four pairs (2 bonding 2 lone pairs )

A

Water

Bent as two lone pairs near top squeeze normal ones down

6
Q

Examples of a trigonal bipyramidal and octahedral

A

Trig bi = PCl5

Octahedral = Sf6
