Learning Activity 1 Preparation of Acetanilide Abstract Recrystallization is a common method of purifying organic substances through the difference in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution‚ molecules of other compounds

DV 1. Customer satisfaction 1. Customer satisfaction is a key factor in formation of customer’s desires for future purchase (Mittal & Kamakura‚ 2001). 2. Furthermore‚ the satisfied customers will probably talk to others about their good experiences. This fact‚ especially in the Middle Eastern cultures‚ where the social life has been shaped in a way that social communication with other people enhances the society‚ is more important (Jamal & Naser‚ 2002). 3.

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)
