yus hang on i can figure this out

this is Ph-CH2-O-CH2CH3 right

hydrogen protonates oxygen giving it a plus charge

and then oxygen breaks the bond closer to the ring and takes both its electrons to form CH3CH2OH

because the resulting carbocation after that is resonance stabilized

and then iodine goes onto that carbocation making Ph-CH2I

i.e, Sn1 reaction

Ether ka cleave krke dekho kaha Carbocation stable banra hai
