Answer #1

The concept in this question is that, the more the alkene is substituted the more stable it is. So when all the four hydrogen is substituted by a R or hydrocarbon group, more stable it is.

Here in this question, only in option 2, all the H is replaced by R group. Hence 2,3,4-trimethyl-3-hexene is the most stable of all.

Please find the attached image for more understanding.

Hope it Helps!!

Thanks..
