Williamson ether synthesis is an organic reaction, forming an ether from an organohalide anda deprotonated alcohol(alkoxide). It involves the reaction of an alkoxide ion with a primary alky halide via SN2 reaction. The reaction to form propoxypropane using Williamson reaction is as shown
CH3CH2CHONa + CH3CH2CH2Br = C2H5CH2-O-CH2C2H5 + NaBr
Sodium propoxide 1-Bromopropane 1- Propoxypropane
Glucagon is <span>protein hormone that is produced by the pancreas to promote the increase in the sugar content of the blood by breaking down glycogen in the liver.</span>
