Question #8e96a

Answer 1

The `CO_2` molecule has a straight-line configuration `O=C=O` so it has no dipole moment.

Explanation:

`NO_2` has an angle:

So there IS a dipole (the `O`-side being slightly more negative).
The `O`'s will be attracted by the slightly positive `H`'s from the water molecules, and the `N` by the `O` of the water.

In short: polar in polar.
