3. Post Lab: Question 2 Using the CRC Handbook of Chemistry and Physics make a table with the two compounds assigned to you. The headings for the table are shown below.
Compound CAS MW mp/bp Density Solubility Liquid/
No. (°C) (g/ml) Solid
2A. 2-chloro-5-methylphenol
2B. 3,5-dinitrotoluene
5. CRC Sample Page Chemicals are arranged alphabetically
Different purities and forms
Usually the first entry for a compound is what you want.
