Vedclass · Answer

(A) $1$. Analyze the $IUPAC$ names of the given structures:- Structure $(1)$: The longest chain has $7$ carbons. It is $3-$ethyl$-4-$methylheptane.- Structure $(2)$: The longest chain has $7$ carbons. It is $3, 5-$dimethylheptane.- Structure $(3)$: The longest chain has $7$ carbons. It is $3-$ethyl$-4-$methylheptane.- Structure $(4)$: The longest chain has $7$ carbons. It is $3-$ethyl$-4-$methylheptane.$2$. Comparing the names,structures $(1), (3),$ and $(4)$ are identical compounds ($3-$ethyl$-4-$methylheptane),while structure $(2)$ is an isomer of the others.$3$. Therefore,the statement that $1, 3,$ and $4$ represent the same compound is correct.
