first oxidise alcohol to aldehyde or ketone then if oxidised product contain CH₃C=O gp then it will undergo haloform
now check

the halogen taken in haloform reaction oxidises the hydroxy group so we dont have to oxidise it first

But gagar sir, both compounds are primary alcohols, aren't they. So both will answer iodoform/ haloform? [7]

no arogorn in haloform reaction the heterolytic cleavage of the c-c bod by water is a very imp step and only those carbons having three halogens can show this type of step so in case of ethyl alcohol this thing is posible while in case of n-propyl alcohol it is not possible

and yes both can oxidise
