Some OWLv2 questions require you utilize the ChemDoodle Sketcher tool to draw a model of a molecule.

ChemDoodle Sketcher lets you describe the structural formula of a molecule by adding atoms, bonds, and rings to your model using the buttons at the top.

A question might begin with the ChemDoodle Sketcher displaying a unmarried atom, an undefined dot, or a model that is nearly complete for you to finish.

  1. Draw the structural formula.
    To practise this Do this
    Add together atoms
    1. Click the down arrow next to the chemical element button.

      options for commonly used elements

    2. Select an element.

      Cull from the displayed options, or click display periodic table to choose from the periodic table.

    3. Click an existing element in ChemDoodle Sketcher and drag away.

      The selected element is added to the structual formula.

      options for changing the attributes of an atom

    2. Click add radical to add a radical, or remove radical to remove a radical.
    3. Click an cantlet.
    Characterization an atom with an asterisk
    1. Click the downward arrow next to the attributes button.

      options for changing the attributes of an atom

    2. Click any element .
    3. Click an cantlet.

    2. Click Rgroup .
    3. Click an atom.
    4. Enter a positive integer in the Input window.
    Draw bonds

    To describe a bail with carbon at the other terminate:

    1. Select a bail type.

      types of bonds

    2. Click an existing atom.

    To describe a bail with an element other than carbon at the other end:

    Notation This can only be done with unmarried bonds, simply you can edit the bond after.

    1. Select the single bond.
    2. Select an element.
    3. Click and elevate away from an existing cantlet.
    Draw rings
    1. Select a ring blazon.

      types of rings

    2. Click an cantlet or pair of atoms.
    Enclose a region with brackets
    1. Click bracket.
    2. Click and drag to select the region to enclose with brackets.
    3. Use the three sets of arrows around the brackets to ascertain the following values:
      • Accuse amount: tiptop-right arrows
      • Repeat count: bottom-right arrows
      • Multiple count: center-left arrows
  2. Edit the structural formula.
    To do this Do this
    Edit atoms
    1. Click the down arrow next to the element push button.

      options for commonly used elements

    2. Select an element.

      Cull from the displayed options, or click display periodic table to choose from the periodic tabular array.

    3. Click an element in ChemDoodle Sketcher to set information technology to the selected element.
    Edit bonds
    1. Select a bail blazon.

      types of bonds

    2. Click an existing bond.
    Motion objects
    1. Click move.
    2. Click and drag an object.
    Erase an object
    1. Click erase.
    2. Click an object.
    Disengage your last activity Click undo.
    Redo your final action Click redo.
    Clear all objects Click clear.
  3. Click Submit Respond.

Example

Instructions:

Draw a complete construction for a molecule with the molecular formula CH4S.

  • Explicitly draw all H atoms.
  • In cases where at that place is more than ane answer, simply draw one.

Note The question begins with the ChemDoodle Sketcher tool displaying a unmarried carbon atom.

the ChemDoodle Sketcher tool displaying one carbon atom.

Answer:

  1. Click single bond , and click the carbon cantlet.

    Two carbon atoms connected by a single bond.

  2. Open up the dropdown carte adjacent to the element button, and select Due south.
  3. Click the new carbon atom to change it to an sulfur atom.

    A carbon atom and a sulfur atom connected by a single bond.

  4. Click single bond , and click the sulfur cantlet.
  5. Open the Set Label dropdown card and select H.
  6. Click the new carbon atom to modify it to a hydrogen atom.

    A sulfur atom connected to a carbon atom and a hydrogen atom by single bonds.

  7. Click single bond , and click the carbon atom.
  8. Select H, and click the new carbon atom.

    A carbon atom connected to a sulfur atom and a hydrogen atom by single bonds. The sulfur atom is connected to another hydrogen atom by a single bond.

  9. Click recessed bond , and click the carbon atom.
  10. Select H, and click the new carbon cantlet.

    A carbon atom connected to a sulfur atom and a hydrogen atom by single bonds, and another hydrogen atom by a recessed bond. The sulfur atom is connected to a third hydrogen atom by a single bond

  11. Click protruding bond , and click the carbon atom.
  12. Select H, and click the new carbon cantlet.

    A carbon atom connected to a sulfur atom and a hydrogen atom by single bonds, a second hydrogen atom by a recessed bond, and a third hydrogen atom by a protruding bond. The sulfur atom is connected to a fourth hydrogen atom by a single bond.
