The reaction of 4 -methyloct- 1 -ene ( P , 2 . 52 g ) with HBr in the presence of C 6 H 5 CO 2 O 2 gives two isomeric bromides in a 9 : 1 ratio, with a combined yield of 50 % . Of these, the entire amount of the primary alkyl bromide was reacted with an appropriate amount of diethylamine followed by treatment with aq. K 2 CO 3 to give a non-ionic product S in 100 % Yield. The mass (in mg ) of S obtained is [Use molar

Step-by-step solution
The 1-alkene undergo addition reaction and major product formed according to anti-Markonikov's rule. Moles of P = Mass   of   P Molar   mass   of   P = 2 . 52 252 = 0 . 01   mol Given that isomeric bromides formed have the mole fractions 9 10 and 1 10 Moles of A (major product) = 0 . 02 × 9 10 × 50 100 = 0 . 009   mol Now the alkyl bromide formed undergo nucleophilic substitution reaction with diethyl amine and potassium carbonate. In the above reaction, the product
