Answer:The image shows three displayed formulas of organic molecules. - The first molecule is but-2-ene, a hydrocarbon with a double bond between the second and third carbon atoms. Its formula is CH3CH=CHCH3- The second molecule is pent-2-ene, a hydrocarbon with a double bond between the second and third carbon atoms. Its formula is CH3CH=CHCH2CH3- The third molecule is but-1-ene, a hydrocarbon with a double bond between the first and second carbon atoms. Its formula is CH2=CHCH2CH3HOPE IT HELPS YOU BETTER
