The question asks you to write the structural formula for 2-methyl-2-butene, I know how to go about solving this but I had two other questions:

1) For a structural formula is it incorrect to include the double bonds in the formula? For instance (CH₃)₂C=CHCH₃? Or should I not include the double bond because it is implied?

2) Additionally, I first got the answer CH₃CHC(CH₃)₂ which is the given answer but backwards. Does that mean my answer is incorrect or can the structural formula be written either way?

1) It's fine to do it like that. Actually, adding the double bond shows your understanding that it's an alkene.

2) It's not incorrect. It's essentially the same thing. As long as the structure is the same, doesn't matter if its flipped.
