1. Chem 108 library session answer key

3. 5.1 Me 3 Si–O–SiMe 3

4. How many results do you find when you conduct a substructure search? – 44 Think about the structures you viewed and compare them to the structure you drew originally (HMDSO). Is there a pattern? (In other words, how are these compounds related to your original structure?) – The original structure (the connectivity of elements) is a part of the retrieved molecule

5. What do you think a substructure search is doing? Think sub and structure. – if you draw a chemical fragment or pattern, it will retrieve molecules that contain that fragment or pattern

6. 11 - What is HMDSO’s molecular weight? – 162.379 Synthetic use? – reagent for synth. of benzoyl chlorides; silylating agent for conversion of alcohols → silyl ethers; silylates carboxylic acids in presence of catalytic H2SO4 a reference article that provide the Si-29 NMR spectra – Harris, R.K. et al., J. Magn. Reson., 1975, 17, 174 HMDSO synthesis – Synth. from Me3SiCl + H2O
