Question

Question: (a) Give an acceptable name for each compound. (b) Draw the organic products formed when A or B is treated with each reagent: [1]${\mathbf{H}}_{\mathbf{3}}{\mathbf{O}}^{\mathbf{+}\mathbf{}}\mathbf{}\mathbf{;}\mathbf{\left[}\mathbf{2}\mathbf{\right]}{\mathbf{}}^{\mathbf{-}}\mathbf{OH}\mathbf{}\mathbf{,}\mathbf{}{\mathbf{H}}_{\mathbf{2}}\mathbf{O}\mathbf{}\mathbf{}\mathbf{;}\mathbf{\left[}\mathbf{3}\mathbf{\right]}\mathbf{}{\mathbf{CH}}_{\mathbf{3}}{\mathbf{CH}}_{\mathbf{2}}{\mathbf{CH}}_{\mathbf{2}}\mathbf{MgBr}\mathbf{}$(excess), then ${\mathbf{H}}_{\mathbf{2}}\mathbf{O}$; [4] ${\mathbf{LiAlH}}_{\mathbf{4}\mathbf{}}\mathbf{,}\mathbf{}\mathbf{Then}\mathbf{}{\mathbf{H}}_{\mathbf{2}}\mathbf{O}$, then .

Short answer

Answer

a. The name of compound A is Isobutyl 2,2-dimethyl propanoate.

The name of compound B is 3-Cyanoheptane.

b.

Step-by-step solution

Step-by-Step SolutionStep 1: Grignard reagent

Grignard reagents are compounds that have the general formula RMgX, where R is an alkyl or aryl group and X is a halogen (chlorine, bromine, or iodine) atom.

Since magnesium is highly electropositive due to the electron-withdrawing nature of the halogen, the carbon atom connected to it has a partial negative charge (carbanion).
