Using the symbols d+ and d-, label all polar covalent bonds for a. the molecule in Problem 4.60b. b. the molecule in Problem 4.61. For this problem, you may need to partially redraw the molecules using Lewis notation. Using the symbols d+ and d-, label all polar covalent bonds for a. the molecule in Problem 4.55b. b. the molecule in Problem 4.56b.
