The stability of isomers is determined by the amount of steric hindrance and the type of bonds present.

1. 2-methylpropene: This is a branched alkene, which means it has a higher degree of steric hindrance than the other options. This makes it less stable.

2. cis-2-butene: This is a cis isomer, which means the bulky groups are on the same side of the double bond. This causes more steric hindrance and makes it less stable than its trans counterpart.

3. 1-butene: This is a terminal alkene, which means the double bond is at the end of the molecule. Terminal alkenes are generally less stable than internal alkenes.

4. trans-2-butene: This is a trans isomer, which means the bulky groups are on opposite sides of the double bond. This reduces steric hindrance and makes it more stable.

So, the most stable isomer among the given options is trans-2-butene.
