Question

of the following alkenes is expected to have the highes heat of hydrogenatio? expected to have the highest heat of hydrogenation? (A 1-pentene B) trarls-2-pentene C) cis-2-pentene D) 2-methyl-2-butene hich alkene below is thermodynamically the most stable? 1-hexene Brans-3-hexene C) cis-3-hexene D2-methyl-2-pentene 64. The stereochemical pathway for the hydrogenation of an alkene with a metal catalyst. such as platinum, occurs via syn addition. anti addition. C) Markovnikov addition. D) anti-Markovnikov addition. B) 65. The product(s) in the following reaction is(are) Cth Pd H3C A) only trans-1-4-dimethylcyclohexane. only cis-1-4-dimethylcyclohexane both trans and cis-1-4-dimethylcyclohexane. uy methylcyclohexane.

Explanation / Answer

Ans 63 - D) 2-methyl-2-pentene

The compound has highly substituted double bond containing carbon atom and also the primary carbanions are more stable than secondary or tertiary , so the compound is likely to be most thermodynamically stable than all the other alkenes shown.
