The liquid which has the stronger intermolecular attractive force between water and honey is to be stated and the corresponding answer is to be explained. Concept introduction: The tendency of the particles to stick together is known as intermolecular attraction. Liquid has several measurable properties that depend on intermolecular attractions. A sphere has the smallest surface area possible for a drop of any given volume. This tendency towards a minimum surface is the result of the surface tension.

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. 1 Number of signals in the 'H NMR spectrum. 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. 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 at right. O ✓ No additional Hs to color in top molecule ง No additional Hs to color in bottom…
