Which shown alkene has the highest heat of hydrogenation?
Options:
Answer:
A
Solution:
Hydrogenation is most exothermic for the least stable alkene. (1) has a monosubstituted terminal alkene; (2) is disubstituted and (3),(4) are more substituted. Alkyl substitution stabilises the latter, so (1) has the largest heat of hydrogenation. Printed choice 1.
