Alkenes on Silicon and Silica

Vinyl groups of alkenes react with hydrogen-terminated or hydroxyl-terminated groups on silicium surfaces, according to 

The R-group may be an oligomer or polymer of which the degree of polymerization and therewith the chain length can be well controlled. This provides a way to apply, for instance, uniform polymer brushes on such silicon or silica surfaces (see also Section 20.4.3). 

2 In 1765, Benjamin Franklin described experiments that he had done on Clapham pond near London (see Section 1.3). He observed that a teaspoon of oil (2.5 cm ) placed on the water surface would cahn the surface up to 3000 m. Use this to estimate the size of a molecule (assume that the oil forms a mono-layer). Assuming that the oil was oleic acid with a molar mass of 282 g moL and a density of 0.895 gcm, calculate the thickness of the layer and the area per molecule. Compare the results with the dimensions of an oleic acid molecule. 

The figure shows the equilibrium surface tension y of aqueous butanol solutions as a function of the butanol concentration c in water, at 25°C. Derive the pressure-area isotherm, for the soluble butanol monolayer.
