13: Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols. Alcohols are inexpensive materials and easy to maintain. However‚ they are a poor leaving group the OH group is a problem in nucleophilic substitution‚ this problem is fixed by converting the alcohol into H2O. Objective: The objective of this lab is to observe the synthesis of 1-bromobutane in an SN2 reaction‚ to see how a primary alky

The E2 reaction performed began by dehydrohalogenating the 3-chloro-3‚ 7-dimethyloctane with potassium hydroxide in aqueous ethanol. The 3-chloro-3‚ 7-dimethyloctane will lose a hydrogen from three different carbons that cause the formation of three constitutional isomers. If the hydroxide ion attacks a hydrogen on the 3-methyl carbon‚ then 2-ethyl-6-methyl-1-heptene will be the product. If a hydrogen on the carbon-2 was attacked‚ then the product would be 3‚ 7-dimethyl-2-octene. If a hydrogen was

Unit Eight – E2 ‘’Collate information about how care for children may be provided within families and society’’ ‘’Child care (or "childcare"‚ "child minding"‚ "daycare"‚or "preschool") is the caring for and supervision of a child or children‚ usually from newborn to age thirteen. Child care is the action or skill of looking after children by a day-care centre‚ babysitter‚ or other providers. Child care is a broad topic covering a wide spectrum of contexts‚ activities‚ social and cultural conventions
