In alkenes there are four groups bonded to the carbons which constitute the carbon-carbon double bond. Which of the following situations produces cis-trans isomensm none of these results in the existence of cis-trans isomerism when all four groups are the same when the two groups on one atom are the same, but the two groups on the other atom are different from each other and also different from the groups on the first atom when three of the four groups are the same, but the fourth group is different Moving to another question will save this response. Which of the following is not a correct IUPAC name for an alkene? 2-methyl-3-butene 2-methyl-1-butene 2-methyl-2-butene None, these are all correct IUPAC names. Moving to another question will save this response. Moving to another question will save this response. Question 11 Which of the following is true in the IUPAC system for naming alkenes? None of the above is correct. The alkene is always named based on the longest carbon chain. The position of the double bond is always given the highest possible number. The position and identity of substituents determines the number associated with the position of the double bond. Moving to another question will save this response
