Answer 1

Hi Brainly Helper bro here is your answer

____________________________

CH3 CH2 I + KOH(aq) ---->CH3 CH2 OH + KI

This given reaction will be nucleophilic substitution reaction because the hydroxy group with the lone pair itself act as nuclophile and will substitute iodide to form ethanol

Answer 2

Nucleophilic reaction : Nucleophile are nucleus loving chemical species.and you know,
Nucleophiles always attack the substrate molecule at the site of the the lowest electron density.
substitution reaction :- the reaction in which one species is replaced by other species is known as substitution reaction.
Here, you can see that Nucleophile I- is replaced by the Nucleophile OH- .
CH3CH2I + KOH --->CH3CH2OH + KI
Hence, this is the example of Nucleophilic substitution reaction.
so, option (b) is correct
