Consider the mechanism for the reaction of cyclohexene and bromine at $-5C$ in $CC{l}_4.$ The bromines in the equation are

numbered to differentiate them in the mechanistic steps.

Identify the curved arrows needed for the mechanism, then draw the key intermediate and product. Clearly show

stereochemistry, by drawing a wedge and dash bond at each chirality center $($including hydrogen atoms$).$ Draw one enantiomer

for any racemates.

A$.$ Select the curved arrow$($s$)$ needed for step $1.$

A curved arrow starts from the lone pair of bromine

$1$ and points to an alkene carbon.

A curved arrow starts from the $Br-Br$ bond and

points to bromine $2.$

Two curved arrows start on bromine $1,$ each pointing

to an alkene carbon.

A curved arrow starts from the alkene $$ bond and

points to bromine $1.$

B$.$ Draw $1$ organic species and $1$ inorganic species

formed in step $1.$ Include charges and

non$-$bonding electrons.Consider the mechanism for the reaction of cyclohexene and bromine at $-5\backslash$deg C in CCI. The bromines in the equation are numbered to differentiate them in the mechanistic steps.
