How does the structuaral formula of butane and butene differ? Chemistry Matter Basic Atomic Structure 1 Answer anor277 May 11, 2018 You gots #C_4H_10# versus #C_4H_8#...the LATTER formula has ONE so-called degree of unsaturation. Explanation: And #C_4H_10# can form TWO structural isomers. Butylene can form FOUR structural or geometric isomers...the which are... #H_2C=C-CH_2CH_3# #"1-butylene"# #H_3C-CH=CHCH_3# #"2-butylene"#; how many geometric isomers can this form...? #"isobutylene"# #(H_3C)_2C=CH_2# #C_4H_8# can FORM TWO ring structures (and the ring ALSO REPRESENTS one degree of unsaturation).
