PMT 2 This question is about two isomeric halogenoalkanes, P and Q. (a) A hot aqueous solution of silver nitrate is added to each halogenoalkane. Both halogenoalkanes react to form a yellow precipitate. (i) Identify, by name or formula, this yellow precipitate. (1)of the isomers. (ii) The isomers have relative molecular mass 169.9. Deduce the molecular formula (1) (1) (1) (iii) Halogenoalkane P forms the yellow precipitate faster than halogenoalkane Q. Draw a displayed formula for halogenoalkane P. (iv) Give the name or structural formula of the alcohol, R, formed by the reaction of halogenoalkane, P, with hot aqueous silver nitrate.*N35693A0416*<br /> PMT (b) When R is boiled with a mixture of potassium dichromate(VI) and dilute sulfuric acid, the organic product S forms. (i) Give the colour change you would expect to see. (2) Fromto(ii) Give the name of S. (1)(iii) Give the type of reaction involved in the conversion of R to S.
