Image for Which of the following molecules has a dipole moment? A) CCl4 B) CO2 C) Cl-C C-Cl D) CH2Cl2 E) Br 15) Which o

Answer

Question 14. dipole moment = must form a dipole, positive and negative, due to electron distribution a) CCl4 –> nonpolar, perfect tetrahedrical shape b) CO2 –> nonpolar, C=O bonds cancel each other due to 180 ° c) Cl-CC-Cl –> nonpolar, Cl bonds cancel each other due to 180 ° d) CH2Cl2 –> Tetrahedral, but will form + dipole in H and – dipole in Cl- this is DIPOLAR

e) C2Br2H2 –> nonplar, Br and Br dipoles cancels out
