CH3COCH3 (acetone) is a common laboratory solvent that is often used in nail polish remover. Its Lewis structure and space-filling molecular image are shown here: Acetone is a polar molecule; the oxygen end has a slightly negative charge (oxygen is more electronegative), whereas the carbon and hydrogen end has a slightly positive charge. In liquid acetone, the molecules are attracted to each other via these polar ends-the positive end of one molecule is attracted to the negative end of its neighbor-and therefore align as shown here: Draw a Lewis structure and space-filling molecular image for CH2Cl2 (dichloromethane), another common laboratory solvent. Is the molecule polar? Which end of the molecule has a slightly negative charge? Which end has a slightly positive charge? Draw several space-filling molecular images of CH2Cl2 showing how they align in liquid dichloromethane.

A classmate of yours is convinced that he knows everythingabout electronegativity. (a) In the case of atoms X and Y havingdifferent electronegativities, he says, the diatomic moleculeX¬Y must be polar. Is your classmate correct? (b) Yourclassmate says that the farther the two atoms are apart in abond, the larger the dipole moment will be. Is your classmatecorrect?
Draw a molecule that has a trigonal pyramidal geometry using D as the central atom and G as the outer atoms picture does not have to show 3 dimensions and outer atoms do not need ione pairs. G is more electronegative than D State wether this molecule is polar or non polar? What are it's bond angles?
why are some gases polar molecules? For example, SO2 is a polar molecule and a gas. CHCl3 is a polar molecule but a liquid. How come these two examples are both polar molecules but are in different states of matter?
CH3F is a polar molecule, even though the tetrahedral geometry often leads to nonpolar molecules. Which of the following reasons below explains why CH3F is a polar molecule? A. None of the above gives a valid explanation. B. Even though CH3F has a tetrahedral geometry, the hydrogen atoms in the molecule are more electronegative than the fluorine resulting in the molecule being polar. C. Even though CH3F has a tetrahedral geometry, the carbon atom in the molecule, being the central atom, is more electronegative than the hydrogen and fluorine atoms in the molecule resulting in the molecule being polar.
