Question

Intermolecular Forces 1. (14 pts) The structure of organic monolayers on liquid surfaces details of the molecular interactions, i.e. its structures. Stearic acid has two d domains, hydrophobic and hydrophilic groups a) Circle and label on the following molecular structure to represent these two domains, hydrophobic vs hydrophilic groups depends sensitively on the HHMHMHHMHHHHMMHHH 0 н. с-с-с-с-с-с-с-с-с-с-с-с-с-с-с-с-с-се Steeric acid, a saturated fatty acid b) The structure of a stearic acid film on a water surface is found to be perpendicular to surface. If we use the following graph to represent the "head" and "tail" of a stearic acid, In our lab, we try to form a monolayer of stearic acid molecules that cover the water surface. What happens if we add too much and form a second layer (bi-layer)? Draw two layers of stearic acid molecules by showing clearly their orientations on the following water surface.
