3 doubts

(1)CHâ‰¡CH react with Cu₂cl₂ and NH₄Cl to form A. A reacts with 1eq H₂ and give B. Find A and B.

(2)Mendelic amide reacts with Br₂/KOH to give??

(3)What is the co-ordination number of C in solid (LiCH₃)₄?

please give answer with explanation and also give d strucutre of Mendelic amide.

(1)A will most probably be Cu-Câ‰¡C-Cu
acidic hydrogens replaced by Cu....

for the 3rd one is the ans 6 ? it forms a octahedron in solid state with alternating Li and CH₃ at the edges.

ans is 7 for d 3rd one. Ayone can give d ans of 2nd one.

From wiki (mandelic acid). So hoffman degradation yields Ph - CH(NH₂)(OH)

answer 1: B is buta-1,3-diene and A is buta-1-en-3-yne

yup!! Pritish is right.. @lubu: you can check it by mechanism.
