Explanation / Answer

Q2

Lewis structures:

H-O-O-H

O=O

O=O-O (resonance)

then

average bond in O-O = sinlge bond, so O-O is the SHORTEST there is enough strength to form attraction between O-O

then, O3, since it has 1 bond of O=O and 1 bond of O-O

this is via lewis, in real life, there is resonance, which implies that the bond will appear to be 1.5 , that is, not single not double but 1.5x

therefore, it is weaker htan that of O2

O2 has a double bond

O=O is the strongest ,therefore attracts the most O=O

it will be the shortest bond

the order:

O3 < O2 < H2O2
