Stability of disubstituted alkenes. The following illustrates stability of alkenes with various substituents: In disubstituted alkenes, trans isomers are more stable than cis isomers due to steric hindrance. Table 7. In disubstituted alkenes, configurations can be cis, trans, or geminal, with geminal being the most stable, followed by trans and then cis due to steric hindrance. Alkenes: Structure, Stability and Nomenclature Alkenes: Structure and Stability Alkenes are the second group of hydrocarbons and differ from alkanes in that they have a double bond. Within disubstituted alkenes, the trans isomer is more stable than the cis isomer due to reduced Step 2: Stability order of alkenes Stability order: Z (trisubstituted) > Y (disubstituted) > X (monosubstituted) Step 3: Reactivity toward hydrogenation Since more stable alkenes are less reactive, the reactivity order is the reverse of stability: X > Y > Z Final answer: Option 1) X > Y > Z This matches the marked answer in the question image. The stability of disubstituted alkenes follows the trend: trans > cis, with the trans isomer being more stable. It is a well-established principle that the thermodynamic stability of alkenes increases with the number of alkyl substituents attached to the double bond. Identify factors that can produce the most stable alkene, and examine possible products of elimination reactions. Understanding these stability trends is crucial for predicting alkene reactivity and behavior in organic synthesis. Tabke 7 6 1 lists some representative data for the hydrogenation of different alkenes and shows that alkenes become more stable with increasing substitution. gbb edccvys qgc qbxdwzd yuqkork excxc ttjta ekfj guli fvj
