need help with these. will rate thanks

11. Predict the product of the reaction shown below. 1. 2egs3,2,ZnH2O 12. Predict the product of the reaction shown below. 13. Which structure produces only these products upon ozonolysis? (A) (B) (c) (D) 14. Which position undergoes sulfonation ( SO3/H2SO4 ) most rapidly? 15. Which of the indicated hydrogen atoms is most readily abstracted by bromine atom? 16. The reason for my choice (problem #15 ) is the following: A because bromine atom is a very active intermediate; B because an intermediate cation in this position is the most stable; C because the product of bromination is thermodynamically the most stable; D because an intermediate radical in this position is the most stable. 17. Which of the following is NOT an intermediate in the nitration reaction of benzene
