Shapes of structural diagrams-help

[naren11]

What would be the shapes of these molecules? I drew them out but I couldn't still figure out the exact shape names

a. SeO_{3}<br /> <br /> b. HClO_{2}<br /> <br /> c. NO_{2}^{-}<br /> <br /> d.ClF_{5}

The names of the standard shapes can be found in your text or here :

If that doesn't help, describe the shapes and we will tell you the names or tell you if you are making a mistake.
