Question

Arrange the following Alkene in order of relative stability;
a) 1-hexene b) Cis-3-hexene c) Trans-3-hexene d) 2-Methyl-2-pentene e) 2,3-dimethyl-2-butene​

Answer 1

Answer:

don't know the answer

is the answer

Answer 2

Answer:

so order of stability is e>d>c>b>a

Explanation:

Stability of alkenes: A general rule is that, the stability of alkenes increases with increase in the number of alkyl groups (containing hydrogens) on the double bond. It is due to increase in the number of contributing no bond resonance structures.

stability of alkene is judge by no. of α−hydrogens.More the no. α−hydrogen more the will be hyperconjuction more will be stability of alkene. cisalkene is less stable than  trans alkene a has 4 α−hydrogens

b has 2α−hydrogens and cis structure

c has 2α−hydrogens and trans structure

d has 1 α−hydrogens

e has 0 α−hydrogens

so order of stability is e>d>c>b>a
