Question

Consider the following reactions and their heats of combustion.

Using the above information and your knowledge of alkenes, select the statements that are TRUE. 

1-Butene is the most stable compound.

2-Methyl-1-propene is the most stable compound.

1-Butene is the least stable compound.

2-Methyl-1-propene is the least stable compound.

The more carbon atoms attached to the double bond, the more stable the alkene.

A trans isomer is less stable than a cis isomer due to more steric hindrance.

sp² hybridized carbon atoms are more electronegative than sp³ hybridized atoms.
