The properties of water are different from most other substances.

Question

(4 pts - 2 pts each part) A route that can be taken to prepare a hydrophobic (water-repellent) aerogel is to start with trichloromethylsilane, CH3SiCl3 as the silicon source. a. What is the chemical reaction that this undergoes to form a product with Si-OH groups? Write as complete of a chemical equation as you can. CI CI-SI-CH3 CI b. The formation of a byproduct is what drives this reaction - what is the byproduct (if you didn't already answer it in part (a)) and how/why does it form?
