Folasaga

O le 1-penten-3-one o se fa'alapotopotoga fa'aola. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, auala sauniuni ma faʻamatalaga saogalemu o le 1-penten-3-one:

Tulaga lelei:

1-penten-3-one o se vai e leai ni lanu ma se manogi malosi e pei o le ga'o. O lo'o i ai le mamafa o le malamalama fa'atasi ai ma le tele mole mole e 84.12 g/mol.

Fa'aaogā:

O le 1-penten-3-one e tele lona fa'aoga. O se mea mata'utia taua mo le tu'ufa'atasiga o le tele o mea fa'aola i lona tu'ufa'atasiga. E faʻaaogaina foʻi e fai ma mea e faʻaoga i mea manogi ma mea manogi.
