Current Question (ID: 17607)

Question:

$\text{Which of the following compounds will exhibit the lowest heat of hydrogenation?}$

Options:

1. $\text{H}_3\text{C} - \text{CH} = \text{CH} - \text{CH}_3$
2. $\text{H}_2\text{C} = \text{C} = \text{CH}_2$
3. $\text{H}_3\text{C} - \text{CH} = \text{C} - \text{CH}_3$
4. $\text{H}_2\text{C} = \text{CH} - \text{CH} = \text{CH}_2$

Solution:

$\text{Hint: More stable alkene has less heat of hydrogenation}$ $\text{Butadiene shows the smallest heat of hydrogenation due to its higher stability due to resonance.}$ $\text{trans-2-Butene is more stable than cis-2-butene because in trans form bulky groups are opposite to each other and less crowding across the double bond.}$ $\text{The order of stability of alkene is as follows:}$ $\text{Butadiene > trans Butene > cis-2-Butene > 2-methylpropene}$ $\text{The order of heat of hydrogenation is as follows:}$ $\text{cis-2-Butene > trans-2-Butene > 1,3-Butadiene}$
