Question

a) Complete the curved arrow electron-pushing mechanism and predict the major organic product of the reaction when 1-chloropentane is treated with hydroxide in ethanol as shown below. Use curved arrows to show the conversion to the product. Draw the structure of the organic product formed in the reaction. Draw lone pairs. CH3 :ci: СНЫСн,он HO b) Select the option that describes the mechanism of the reaction above. 10 SNI OSN2 Ο Ε1 lo ez

Answer 1

- a) In this first of all we wright reaction CHU OH 1 - The chlozine in the reactant is simply replaced - by oHo hence it is a substitution reaction - Here is the meaharism for the reaction. This is an example of Marlophitic Substitution reaction! Because the mechanism involves Collision between two species in the slow step (in this case only one stop) It is known as SN reaction. A mechanismi-

b) It is a SM² reaction as we discussed because in this the substitution reaction - completed in one step. that's why It is SM² reaction
