Answer 1

[1 - ethyl 6 - methyl - cyclohexone] [1 6 - dimethyl - cyclohexane] implies After change from the system formula [3 - 5 - metheneheptane] most stable form is implies explanation because in this structure minimum hindrance force is present between two molecules [5 5 dimethylhex 2 ol] [5 5 dimethyl 2 hexol] [2 chloro 6 (3-6 dimethyl non or [2 chloro 6 (1 - methylothy) 3 - 6 dimethylnonae] \r\n implies [3 methylcylohex 1 - ah [3 methyl 1 cyclo hexale) (more stable due to less stone hundred force yes it is possible because methyl group is a heavy group which is present at 4th carbon position which is two opposite position so in form more force between methyl group as compare to transe form 14 di methyl cyclo hexane
