Question

The following reaction is classified as: $CH_{3}CH_{2}I+KOH(aq) \longrightarrow CH_{3}CH_{2}OH+KI$ (a) electrophilic substitution (b) nucleophilic substitution (c) elimination (d) addition

Answer 1

A chemical reactions in which an electrophile displaces a functional group in a compound called Electrophilic substitution reactions.

A chemical reactions in which a nucleophile displaces a good leaving group in a compound called Nucleophilic substitution reactions.

A chemical reaction in which two substituents are removed from a molecule is called elimination reaction.

A chemical reaction where two or more molecules combine to form a larger one is called addition reaction.

The given chemical reaction is as follows,

             ${ CH }_{ 3 }{ CH }_{ 2 }I\quad +\quad KOH\quad (aq)\quad \rightarrow \quad { CH }_{ 3 }{ CH }_{ 2 }OH\quad +\quad KI$

It is an example of nucleophilic substitution reaction.

The hydroxyl group of $KOH(O{ H }^{ - })$ with a lone pair of itself acts as a nucleophile and substituents iodide ion in ${ CH }_{ 3 }{ CH }_{ 2 }I$ to form ethanol.

Answer 2

Answer:

This is an example of nucleophilic substitution reaction because the nucleophile I

−

is replaced by the nucleophile OH
