Answer 1

Church H CH 3-ethylhex-a-ene. ch CH CH₂ CH₂ 2-propyl pent-2-ene. different tuPAC Both compound have names. so Both have some molecular formula. Hence Istructoral Isomers/

cis s СУО Chd trans Both compounds have similar location of double bonds & substituents. They differ in the double bond Configuration at Coroon no. Y... Hence Both are geometricel Isment /

Both compoland locatim of differ in the - OH group. are structured Isomer Henco Both
