Question
Na ^+ Na^+ NH2 NH2 Identify the produce of the reaction: CH_3CH=CHbr Mg_rightarrow THF CH_3CH =CHMgBr D_2O_rightarrow CH_3 - CH-CHD CH_2D - CH_2-CH_3 CH_3-CD=CH_2 None of the above Which of these raction sequences will produce m-bromochloribenzene? Bromobenene HNO3/H2SO4_rightarrow H2/pt_rightarrow NaNO2/HCI at 0 C _rightarrow CuCI/delta_rightarrow nitrobenzene H2/pt_rightarrow Br2/Fe_rightarrow NaNO2/HCI at 0 C_rightarrow CuCI/delta_rightarrow nitrobenzene Br2/Fe_rightarrow H2/pt_rightarrow NaNO2/HCI at 0 C_rightarrow CuCI/delta_rightarrow bromobenzene HNO3/H2SO4_rightarrow NaNO2/ HCI at 0C_rightarrow CuCI/delta_rightarrowExplanation / Answer
7) the product formed is,
a)
The carbanion of grignard picks up D+ from D2O to form deuterated strating material.
8) The correct sequence would be,
c)
Nitrobenzene gives m-bromo nitrobenzene in first step. After reduction and diazotization treated with CuCl to form desired product.
