Molecular polarity lab answer key

Molecular Polarity https://goo.gl/zQkLwf This lab does not use the Beyond Labz software Go to the website listed above. Click the play symbol on the simulation. Part 1: Two Atom Investigation (diatomic molecule) ❏ Click the keep the box for bond dipole checked and check the boxes to show the partial charges and the bond character ❏ Keep the electronegativity of A at low and increase and decrease the electronegativity of atom B. Observe the arrow, partial charge and bond character. Fill in the following observation As the electronegativity of atom B increases the... arrow Movies from point A to point B and get bigger toward B partial charges The partial charges on A (+) and partial charge on B (-) they increase and get bigger bond character It will get more iconic ❏ Now put the electronegativity for A to the middle and vary the electronegativity of B and observe the results. Fill in the following information. ● The polarity arrow always points to the ________________________________ electronegative atom. ● The partial positive charge is always on the _____________________________ electronegative atom. ● The larger the electronegativity difference the more __________________________________ the bond character. Part 2: Three atom Investigation ❏ Keep the original “bent” arrangement of atoms and set the electronegativities of A and C to low and B to middle. Click to show the bond dipoles, molecular dipoles and partial charges. ❏ Draw the bond dipoles on the bonds in the diagram ❏ Show the overall molecular dipole in the diagram ❏ Draw the partial charge symbols on the diagram. ❏ Click the reset button. Keep the “bent” arrangement of atoms and set the electronegativities of A and C to high and B to middle. Click to show the bond dipoles, molecular dipoles and partial charges. ❏ Draw the bond dipoles on the bonds in the diagram ❏ Show the overall molecular dipole in the diagram ❏ Draw the partial charge symbols on the diagram. ❏ Click the reset button. Change the arrangement of atoms to a “linear” arrangement (see below) and set the electronegativities of A and C to high and keep B to middle. Click to show the bond dipoles, molecular dipoles and partial charges. ❏ Draw the bond dipoles on the bonds in the diagram ❏ Show the overall molecular dipole in the diagram ❏ Draw the partial charge symbols on the diagram. . ❏ Rotate the molecule to keep the “linear” arrangement (see below) and set the electronegativities of A to high, keep B to middle and set C to low.
