Amines can be made by the reduction of nitriles, which in turn can be made from an alkyl halide. draw the structures of a starting alkyl bromide and the intermediate nitrile that would be used in the synthesis of 3-methylbutylamine (also known as isoamylamine). do not show free ions.

The structrues are shown below.

Explanation:

The compound 3-methylbutylamine has 4 carbons at the principal chain with simple bonds between then (butyl), has a ramification with a CH₃ group at the carbon 3 (methyl), and at the carbon 1 has the amine group NH₂, as shown below.

A nitrile is a compound that has the bond C≡N at the structure, so the nitrile that originates the amide must be the 3-methylbutylnitrile, with the structure shown below (only eliminated the hydrogens from N and carbon, and then added the triple bond).

The alkyl bromide must react with a cyanide salt, which will replace the Br for CN in the compound, so we must replaced the CN for Br in the structure shown below, having the Bromo-2-methylpropane.

the millers tale is the answer.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
