Vedclass · Answer

(A) According to the $CIP$ priority rules,we compare the atoms attached to the first carbon atom of the group.$1: -CH(CH_3)_2$ is attached to $C$ (bonded to $C, C, H$).$2: -CH_2Br$ is attached to $C$ (bonded to $Br, H, H$).$3: -CH_2CH_2Br$ is attached to $C$ (bonded to $C, H, H$).Comparing the first point of difference:Group $2$ has $Br$ (atomic number $35$) attached to the first carbon,which has the highest priority.Group $3$ has $C$ (atomic number $6$) attached to the first carbon.Group $1$ has $C$ (atomic number $6$) attached to the first carbon,but the branching at the second carbon makes it lower priority than the linear chain in group $3$ when comparing subsequent atoms.Thus,the order of decreasing priority is $2 > 3 > 1$.

Rank the following substituent groups in order of decreasing priority according to the Cahn-Ingold-Prelog $(CIP)$ system:
$1: -CH(CH_3)_2, 2: -CH_2Br, 3: -CH_2CH_2Br$
