Answer 1

© L iptor BY 1,2-hydride shitt 2 - carbocation) less stable So a mixture of carbocation. A and B would generate where carbocation - B will have major extent. 3-carbocation) more stable. chz H2 CH₂ CH3 HAC 5 CH₂ 6 3 13,5-trimethylbenzene compound-A 1,3,5-trimethylbenzene compouno- ettz C2 11 3 1 1,2,3 trimethylbenzene compound B 35 crz 2,4-trimethylbenzene compound-c. 32 ctz 1,2,4-trimethylbenzene compound-c compounds are represent. Therefore three different compound - AB f . . н-с LC Markonikovrs rule states that when Hx Chere H-cl) is added to alkane then is added to that - atom cohich has greater no. of o hydrogen atom. In the above an alkene er has greater no of thatom there fore He oftich should have to add on thet c- atom. But cie is added on that co. so this addition does not tollow Markonikovrs.

I Priority & -Bry - OCH3 I D - H Highest priority groups of cac double bond. Hence the alkene is TE] are on the the different side configuration of dfaxial Interaction) HX H₂ a CH₂ axial position cm F e equitorial position In this conformation bulky isopropyl group ( ) is in the axial position there for a strong 43-diaxial Interaction is operate here. which makes the conformation less stable. In this conformation , the bulky soprog isopropyt group (t) is in the equitorial position. Therefore no diaxial interaction with the isopropyl group. But there are 13-diaxial interaction between - and - bout as F has smaller size therefore this is interaction is less strongen than the previous therefore conformation-B is more stable.
