The formula charges on three oxygen atoms of ozone molecule are respectively:

The correct order of the O-O bond length in $$ O_2 , H_2 O_2$$ and $$O_3 $$ is:

The electronegativity difference between N and F is greater than between N and H yet the dipole moment of $$ NH_3(1.5 D) $$ is larger than that of $$ NF_3 (0.2 D) $$. This is because:
