Problem 2PE

Determining a Molecular Formula Mesitylene, a hydrocarbon found in crude oil, has an empirical formula of C3H4 and an experimentally determined molecular weight of 121 amu. What is its molecular formula? Ethylene glycol, used in automobile antifreeze, is 38.7% C, 9.7% H, and 51.6% 0 by mass. Its molar mass is 62.1 g/mol. (a) What is the empirical formula of ethylene glycol? (b) What is its molecular formula?

Step-by-Step Solution:

Answer: Step 1 Mesitylene or 1,3,5-trimethylbenzene is a derivative of benzene with three methyl substituents positioned symmetrically around the ring. The other two isomeric trimethylbenzenes are 1,2,4-trimethylbenzene (pseudocumene) and 1,2,3-trimethylbenzene (hemi melitene). All three compounds have the formula C H (CH 6 3whic3 3commonly abbreviated C H Me . Mesityle6 3 3 is a colourless liquid with sweet aromatic odor. It is a component of coal tar, which is its traditional source. It is a precursor to diverse fine chemicals. The mesityl group (Mes) is a substituent with the formula C H Me and is found in various other compounds. 6 2 3
