Vedclass · Answer

(B) The structure of $2,2$-dimethylbutane is $CH_3-CH_2-C(CH_3)_2-CH_3$.For the given Newman projection,the front carbon has two $CH_3$ groups and one $H$ atom,while the back carbon has two $H$ atoms and one group $Y$. The group $X$ is attached to the front carbon.Considering the $C_2-C_3$ bond axis:Front carbon $(C_2)$ has two $CH_3$ groups and one $H$ atom. Back carbon $(C_3)$ has two $H$ atoms and one $C_2H_5$ group.If $X = CH_3$ and $Y = C_2H_5$,this matches the structure.Considering the $C_1-C_2$ bond axis:Front carbon $(C_1)$ has three $H$ atoms. Back carbon $(C_2)$ has two $CH_3$ groups and one $C_2H_5$ group.If $X = H$ and $Y = C_2H_5$,this matches the structure.Comparing with the options,$X=H$ and $Y=C_2H_5$ (Option $B$) is a valid possibility,and $X=C_2H_5$ and $Y=H$ (Option $C$) is also a valid possibility depending on the rotation and projection chosen. Thus,$B$ and $C$ are correct.

In the Newman projection for $2,2$-dimethylbutane,what can $X$ and $Y$ respectively be?
$A$. $H$ and $H$
$B$. $H$ and $C_2H_5$
$C$. $C_2H_5$ and $H$
$D$. $CH_3$ and $CH_3$
