Identify the hydroxyl groups (O−H \rm O\!-\!H) by right-clicking each atom individually on the canvas and then mapping it to M1.

Your post makes no sense.What map? M1? and I have no idea what \rm O\|-\|H means.

To identify the hydroxyl groups (O−H), you will need to visually locate each hydroxyl group on the canvas and then map it to M1. Here's how to do it:

1. Open the canvas that you want to work on.

2. Look for atoms that are bonded to one oxygen (O) atom and one hydrogen (H) atom. These atoms will represent the hydroxyl groups.

3. Place your cursor over the first atom and right-click on it. This will bring up a menu of options.

4. From the menu, select "Map to M1" or any similar option that allows you to label or identify the atom as M1. This will assign the M1 label to the atom.

5. Repeat steps 3 and 4 for each atom that represents a hydroxyl group on the canvas. Right-click on the atom and map it to M1 or any appropriate label.

By following these steps, you will be able to identify the hydroxyl groups (O−H) on the canvas and map them to M1.
