The more carton atoms attached to the double bond, the more stable the alkene. Atrans isomers less stable than a cis isomer de to more stenc hindrance hybridized carbon atoms are more electronegative than sp. hybrdu ed ions.

Ans : There are four correct statements , these are :
2-Methyl-1-propene is the most stable
1-Butene is the least stable compound
The more carbon atoms attached to the double bond , the more stable the alkene.
sp2 hybridized carbon atoms are more electronegative than sp3 hybridized atoms.
The more the double bonded carbon gets substituted , higher is its stability. The stable compounds have lesser heat of combustions than the less stable ones. So here , the most stable one is 2-methyl-1-propene , and the least stable compound is 1-butene.
