Question

Va rog, rezolvarea!!​

Answer 1

CH3-NH2 + HONO(1) ---> CH3-OH + N2 + H2O

CH3-OH + PCl5(5) --> CH3-Cl + POCl3 + HCl

CH3-Cl + KCN(2) --> CH3-C≡N + KCl

CH3-C≡N + 2H2(4) --Ni/toC--> CH3-CH2-NH2

CH3-NH2 + HONO(1) ---> CH3-OH + N2 + H2O

CH3-OH + HBr(3) --> CH3-Br + H2O

CH3-Br + KCN(2) --> CH3-C≡N + KBr

CH3-C≡N + 2H2(4) --Ni/toC--> CH3-CH2-NH2

=> corect B si C
