jquery function on dropdown select

Question

I need to run a jquery function if a certain dropdown option is selected.

<select name=dropdown size=1>
    <option value=1>option 1</option>
    <option value=2>option 2</option>
</select>

I have the commands in the function ready, Im just not sure on how to make it so if option 2 is currently active in the dropdown, then run the function.

(dropdown doesnt have a submit button, i want it ran when the user highlights the option)
