Question “draw the neutral organic products bromocyclohexane”
Draw the neutral organic products.
Answer
General guidance
S 1 (Unimolecular Reaction): The reaction is divided into two parts. The formation of carbocation is the first step. The nucleophile attack against the positive charge is the second. The first step in the formation of product is hybridization of carbocation. This will transform the first sp 3 (tetrahedral), to sp 2 (planar), and then to sp 3 hybridization.
Elimination reaction. Organic reactions are the removal of a group atoms from an molecule through the breaking of the bond between them. This leads to the formation unsaturation.
There are two possible ways that elimination can occur:
1.{{\\rm{E}}_{\\rm{1}}}
2.{{\\rm{E}}_{\\rm{2}}}
The following is the reaction order:
{\\rm{tert - alkyl}}\\,{\\rm{ > }}\\,{\\rm{sec - alkyl}}\\,{\\rm{ > }}\\,{\\rm{pri - alkyl}}The following is the order of the leaving group:
{\\rm{R - X:}}\\,{\\rm{R - I}}\\,{\\rm{ > }}\\,{\\rm{R - Br}}\\,{\\rm{ > }}\\,{\\rm{R - Cl}}\\,{\\rm{ > }}\\,{\\rm{R - F}}It will form stable carbocations, so it has a strong leaving group. It will therefore follow the S N1 reaction mechanism.
u2022 Ionization
\u2022 Deprotonation.
The carbonu2013halogen bonds break during ionization to create a carbocation intermediate. The carbocation is then deprotonated. It is most common in tertiary allyl halides. It can occur in the absence of any base, or with a weak base.
Order of reactivity in the E1 reaction for alkyl-halides:
A {{\\rm{E}}^{\\rm{1}}} {{\\rm{E}}_{\\rm{1}}}
Step-by-step
Step 1 from 2
Common mistakes
The compound cyclohexylbromide is a secondary alkyl-halide. It can undergo substitution or elimination reactions. The formation of a carbocation is the first step in the reaction. The second step is either substitution or elimination. Two products can be expected to be made.
Step 2 from 2
On reaction of the given product, cyclohexylalkyl halide with hydroxide ion it produces two products. The first step results in the formation of the carbocation. The substitution product is cyclohexanol, which eliminates hydrogen and forms cyclohexene when water is added.
