When the following molecule reacts with Br₂/FeBr3, substitution occurs at [x] to yield the major product. Please write the number of the corresponding carbon (i.e., 12). 9 cha 4 NO₂ 3

By which substitution mechanism (SN1 or SN2) did the reaction occur? How did you know? For what reason does the substitution occur at only one of the bromine atoms, and in particular the bromine atom that it did?

Write an additional resonance contributing structure for each carbocation and state which of the two makes the greater contribution to the resonance hybrid.

Draw An energy diagram for the SN1 reaction: (CH3)3CBr+ CH3CO2−→(CH3)3COCOCH3 + Br−

Stereochemistry: Assign each of the following alkenes as E or Z or unassignable. Also assign each of the following alkenes as cis or trans or not applicable.

Draw a structural formula for the product of each SN2 reaction. Where configuration of the starting material is given, show the configuration of the product.

Provide a short answer for why the secondary alkyl halide is the major product versus the tertiary alkyl halide from free radical halogention H₂C NBS H₂C, Br H₂C むーびず H peroxides Br + enantiomer + enantiomer Major Minor

The two alkenes below react with HI at different rates. CH3CH=CHCH3 and CH₂=CH₂ Draw the structural formula of the MAJOR product formed by the alkene having the HIGHER reaction rate. • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one.

I am confused as to how to do this problem.  Does the double bond change anything?
