CCO Magnify O=P(O)(O)O
(heated, concentrated)
C=C Magnify

DISFAVORED: Acid-catalyzed dehydration is not effective for primary alcohols. POCl3 would be a better method.
CC(C)O Magnify O=P(O)(O)O
(heated, concentrated)
CC=C Magnify

Note: Acid-catalyzed dehydration (E1)
CC(C(C)(C)C)O Magnify O=P(O)(O)O
(heated, concentrated)
CC(=C(C)C)C Magnify

Caution: Acid-catalyzed dehydration by E1 mechanism is susceptible to carbocation rearrangement
