The liquid water is denser than solid ice. This important to aquatic life and weather has to be explained. Concept introduction: Hydrogen bonding : Hydrogen bonding is weak attractive force that occurs between hydrogen atom bounded to high electronegative atom such as Nitrogen, Oxygen or Fluorine and another adjacent atom having a lone pair of electrons. Hydrogen bonding in water molecule : Hydrogen bond involves a hydrogen atom of one water molecule bounded to a lone pair of electrons on Oxygen atom of another molecule of water. Figure.1

Question 11 of 18 (1 point) Question Attempt: 3 of How many signals do you expect in the 'H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. 1 For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule Check For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box…
