	Friedel-Crafts Test for aromatic hydrocarbons. Heat test tube containing 50 mg anhydrous aluminum chloride to sublime the salt. (Williamson, 3rd Ed., p758) Figure 7.21
	Friedel-Crafts Test for aromatic hydrocarbons. After cooling the sublimed salt, add a soln of 8 drops or 10 mg of unknown in 2 drops chloroform. Positive test showing red color for 1,2,3-trimethylbenzene. (Williamson, 3rd Ed., p758) Figure 7.22
	Friedel-Crafts Test for aromatic hydrocarbons. After cooling the sublimed salt, add a soln of 8 drops or 10 mg of unknown in 2 drops chloroform. Positive test showing dark blue-green color for naphthalene. (Williamson, 3rd Ed., p758) Figure 7.23
	Friedel-Crafts Test for aromatic hydrocarbons. After cooling the sublimed salt, add a soln of 8 drops or 10 mg of unknown in 2 drops chloroform. Positive test showing yellow-orange color for benzaldehyde. (Williamson, 3rd Ed., p758) Figure 7.24
	Friedel-Crafts Test for aromatic hydrocarbons. After cooling the sublimed salt, add a soln of 8 drops or 10 mg of unknown in 2 drops chloroform. Negative test showing no color change for 3-octanone. (Williamson, 3rd Ed., p758) Figure 7.25

Aromatics
Ignition Test: see Ref: (Pavia et.al., 3rd Ed., pp 447) and compare results by using naphthalene as reference standard.
