Vedclass · Answer

(B) conjugated system is defined as a system of connected $p-$orbitals with delocalized electrons in a molecule,which in general lowers the overall energy of the molecule and increases stability. In conjugated dienes,two double bonds are separated by exactly one single bond,represented as $C=C-C=C$. $1, 3-$butadiene $(CH_2=CH-CH=CH_2)$ and $1, 3-$pentadiene $(CH_2=CH-CH=CH-CH_3)$ both contain conjugated double bonds. However,in standard multiple-choice questions of this type,$1, 3-$butadiene is the fundamental example of a conjugated diene. Note: Both $B$ and $C$ are technically correct,but $1, 3-$butadiene is the most common textbook example.
