O ELECTRONIC STRUCTURE AND CHEMICAL BONDING Predicting bond polarity D15 Daniele In each of the molecules drawn below one chemical bond is colored red. Decide whether this bond is likely to be polar or not. If the bond is likely to be polar, write down the chemical symbol for the atom which will have more negative charge. O The highlighted bond is polar and :NEN: the more negative atom is O The highlighted bond is nonpolar. do O The highlighted bond is polar and : Br - Br: the more negative atom is O The highlighted bond is nonpolar. O The highlighted bond is polar and 一 : Br the more negative atom is U - O The highlighted bond is nonpolar Explanation Check Accessibility O 2022 McGraw Hill LLC. All Rights Reserved.
