how to convert formaldehyde to propanol?
Treat it with grignard reagent ( CH3CH2MgBr)
HCHO + CH3CH2MgBr ---------------> CH3CH2CH2OH + Mg(OH)Br
formaldehyde ethyl magnesium bromide
(grignard reagent) propanol
Mechanism:
Since Carbon in grignard reagent is attached to Mg which is more electro +ve than C, it carries a delta minus charge....This carbon attacks the Carbonyl carbon in HCHO ( >C=O ) because it carries delta plus charge....then after hydrolysis (reaction with H2O/H+), propanol is formed..
HOPE THIS HELPS.......BEST OF LUCK.......'LIKE' PLEASE..................
