Question

1. Draw the structure of the unbranched isomer of C5H11Br that is most reactive in an SN1 reaction.
Do not consider stereochemistry.
If there is more than one structure that fits the description, draw them all.

2. Draw the product you expect from the reaction of (S)-3-iodohexane with CH3S-. Be sure to show stereochemistry.

Answer 1

answer to 1st question is :

      H   H H H    H                                                

   |    |    |    |     |

H- C- C- C- C- C- H             

      |    |    |    |     |

     H H Br H H

AND

      H   H H H    H

   |    |    |    |     |

H- C- C- C- C- C- H

      |    |    |    |     |

     H Br H H H

Because S_N1 reaction proceeds in tertiary alkyl halide faster than scondary than primary alkyl halide. Therefore the structures for the given molecular formula is as shown above for S_N1 reaction
