Answer:

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). What are these?
