2 A halogenoalkane, G, has the molecular formula C4H9X, where X represents a halogen atom. On heating G with excess dilute aqueous sodium hydroxide, compound G is converted into compound J, C4H10O. Complete the tables. (a) Test Observation Inference To the solution remaining after heating G with excess dilute aqueous sodium hydroxide, addfollowed by aqueous silver nitrate. White precipitate forms. The atom X is(2) (b) Test Observation Inference Add phosphorus(V) chloride to pure J. Test any gas evolved withWhite smoke The formula of the white smoke isCompound J is an alcohol. (2) *P48371A0416*<br /> (c) Test Observation Inference Warm J with acidified potassium dichromate(VI) solution.Compound J is not oxidised.Compound J is aalcohol. (d) On the basis of the observations and inferences made in parts (a) to (c), draw the structure of compound J. (2) (1) (Total for Question 2 = 7 marks) *P48371A0516* Turn over<br />
