Questions: A variety of hexene derivatives are shown below. List them in order of increasing stability: (1pt) A B C E Ranking:

Solution Steps

• A: 1-hexene (terminal alkene)
• B: 2-methyl-2-butene (trisubstituted alkene)
• C: 2-hexene (disubstituted alkene)
• D: 3,3-dimethyl-1-butene (disubstituted alkene)
• E: 2,3-dimethyl-2-butene (tetrasubstituted alkene)

• Terminal alkenes (like A) are generally less stable.
• Disubstituted alkenes (like C and D) are more stable than terminal alkenes.
• Trisubstituted alkenes (like B) are more stable than disubstituted alkenes.
• Tetrasubstituted alkenes (like E) are the most stable.

• A (1-hexene) is the least stable.
• D (3,3-dimethyl-1-butene) and C (2-hexene) are more stable than A but less stable than B.
• B (2-methyl-2-butene) is more stable than C and D.
• E (2,3-dimethyl-2-butene) is the most stable.
