Chern 204-PSI, 6 . Friedel Crafts Acylation of an Unknown Benzene Compound (One weck lab The Intent of this Lab To acetylate an unknown benzene compound via a Friedel-Crafts acylation and use spectroscopic techniques to determine the acetophenone derivative's identity Introduction The Friedel-Crafts reaction dates back to before 1900 and it is still widely used today. The active electrophilic agent (an acylium ion) is classically prepared and reacts very quickly. Another appealing feature of this reaction is that the acylated...

Q2. Nitric oxide, NO, is a covalent compound that serves several important roles in the body. Draw an electron dot representation of the NO molecule, showing a double bond between the atoms. Q3. The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula C2H2. The covalent compound benzene, a commercial solvent, has the molecular formula C6H6. Each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. Would...
