Unformatted text preview: in both cases. a. 3-buten-1-ol (CH2=CH-CH2-CH2-OH, the 5.0- 6.0 ppm pattern is typical for a terminal alkene attached to a CH2.) b. 1-buten-3-ol (CH2=CH-CH(OH)-CH3, the 5.0- 6.0 ppm pattern is typical for a terminal alkene attached to a CH. Hard to see, but 5.9 ppm peak is a ddd, and the other 2 alkenes are geminal, exhibiting only cis and trans and trans coupling to the alkenyl CH.) 1...
