Fformiwla cyffredinol alcohol Yng Nghemeg , cyfansoddyn organig sydd â'r grŵp gweithredol hydrocsyl (-O H ) wedi ei fondio i atom Carbon grŵp alcyl yw alcohol .
Ffurfio alcohol
Ffurfio halogenoalcanau
Gellir paratio alcoholau cynradd ac eilaidd o halogenoalcanau drwy amnewid niwcleoffilig .
R-X + OH- → R-OH + X-
lle mae X yn grwp gweithredol halogen .
Cyfansoddion carbonyl
Gellir ffurfio alcohol cynradd trwy rydwytho asid carbocsylig neu aldehyd . Defnyddir yr asiantau rhydwytho Lithiwm tetrahydrido alwminad (LiAlH4 ) neu Sodiwm tetrahydridoborad (NaBH4 ).
Asid carbocsylig →Rhydwytho → Aldehyd → Rhydwytho → Alcohol Cynradd
