Vedclass · Answer

(A) Conjugated double bonds occur when two double bonds are separated by exactly one single bond (i.e.,in the pattern $C=C-C=C$).In $hepta-1,3-diene$, the double bonds are at positions $1$ and $3$. The structure is $CH_2=CH-CH=CH-CH_2-CH_2-CH_3$. Here, the double bonds are separated by one single bond at position $2$, making them conjugated.In $hepta-1,4-diene$, the double bonds are at positions $1$ and $4$, separated by two single bonds.In $hepta-1,5-diene$, the double bonds are at positions $1$ and $5$, separated by three single bonds.In $hepta-1,6-diene$, the double bonds are at positions $1$ and $6$, separated by four single bonds.Therefore, only $hepta-1,3-diene$ contains conjugated double bonds.

Among the following, the compound having conjugated double bonds is
