Whether the Friedal-Crafts reaction of benzene with (R)-2-chlorobutane will lead to an optically active or racemic product is to be explained. Concept introduction: The Friedal-Crafts reaction occurs through the formation of a carbocation intermediate. The carbocation is a planar species, as the positively charged carbon is in sp 2 hybridized state. The reaction with the aromatic ring can occur from both sides of the carbocation. Hence normally a racemic mixture is obtained as the product. To explain: Whether the Friedal-Crafts reaction of benzene with (R)-2-chlorobutane will lead to an optically active or racemic product is to be explained.

Predicting the qualitative acid-base properties of salts Consider the following data on some weak acids and weak bases: base acid Κα Kb name formula name formula hydrocyanic acid - 10 HCN 4.9 × 10 pyridine C₂H₂N 1.7 × 10 9 acetic acid HCH3CO2 1.8 × 10 5 hydroxylamine HONH2 1.1 × 10¯ 8 Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. 0.1 M KCN solution pH choose one ✓ 0.1 M C5H5NHCI choose one ✓ 0.1 M NaCH3CO2 choose one ✓ 0.1 M HONH3Br ✓ choose one 1 (lowest) 2 3 4 (highest)
