hybrid structures

isomeric structures

canonical structures

dipole structures.

NH₃

Co^2-₃ 

O₃

SO₃

The relative position of all atoms can differ.

The same number of unpaired and paired electrons in all structures.

Theen ergyof each structure is different.

Like charges are present on adjacent atoms.

BF₃ < H₂S < H₂O

 H₂S < BF₃ < H₂O

H₂O < H₂S < BF₃

BF₃ < H₂O < H₂S

SO₂

CO₂

H₂O

NH₃

the lone pair of nitrogen opposes the dipole moment of NF₃ while it is added to the dipole moment of NH₃

all the dipoles of NF₃ are in same direction

all the dipoles of NH₃ are in opposite direction

NH₃ has a regular geometry while NF₃ has irregular geometry which makes dipole moment of NH₃ more than NF₃.
