[Expelliarmus9]

Can you tell me all alkenes isomers of C₇H₁₄? (only name of them) PLase. Thank you in advance.

CC(C)(C)C(C)=C 2,3,3-trimethyl-1-butene
CC(C)C(CC)=C 2-ethyl-3-methyl-1-butene

There's aslo the cyclic alkanes, but you specified the alkene isomere

[Expelliarmus9]

thank you very much:) but I have a question: why doesn't exist 2 - ethyl 3-methyl 1- butene?

, because I missed it.

CC(C)C(CC)=C 2-ethyl-3-methyl-1-butene
