Identify any polar covalent bonds by drawing dipole arrows in the appropriate locations.

For each compound, determine the direction of bond polarity. Leave the box blank for a nonpolar bond. Br—Br H—Cl F—CH3

Fill in the lone pairs needed to give the main group elements (except hydrogen) an octet. Glycerol is a product of the metabolism of fats. Acrylamide is used to make polyacrylamide, which is used in some cosmetics and food packaging.

Drag the gold star onto the molecule with the largest charge separation and largest bond dipole moment. Don't look up the electronegativity values! Use your understanding of how electronegativity changes in the periodic table. F-F N-CI N-F Cl-CI N-O O-F

Directions: Arrange the following substances according to increasing polarity by getting the difference in the electronegativities of the atoms in the compound. You may use your periodic table as a reference for the electronegativity of the elements. In the case of compounds with multipie elements, get the difference in electronegativity of the encircled elements. Least polar substance Most polar substance H-C=N H-H Н-F Na - Cl H-О-Н

Show the direction of the dipole in each bond. Label the atoms with δ+ and δ−.

Draw a Lewis structure for fulminic acid, HONC or HCNO, adding charges and lone electron pairs to the appropriate atoms. Explicitly draw all H atoms. Include all valence lone pairs in your answer. opy aste H-C=N=Q
