Question

Classify the type of following reaction: $(CH_{3})_{3}C-CH_{2}OH+HBr \longrightarrow (CH_{3})_{2}CBrCH_{2}CH_{3}+H_{2}O$

Answer 1

"A "substitution reaction" is a "type of chemical reaction" in which "another atom" or "functional group" of a molecule is replaced. It is also called a "single replacement reaction".

The given reaction is as follows,

${ \left( { CH }_{ 3 } \right)  }_{ 3 }C-C{ H }_{ 2 }OH\quad +\quad HBr\quad \rightarrow \quad { \left( { CH }_{ 3 } \right)  }_{ 2 }CBr{ CH }_{ 2 }{ CH }_{ 3 }\quad +\quad { H }_{ 2 }O$

From the above reaction, $OH^{ - }$ of the ${ \left( { CH }_{ 3 } \right)  }_{ 3 }C-C{ H }_{ 2 }OH$ added to the ${ H }^{ + }$ of the HBr.

Therefore, substitution takes place followed by rearrangement of atoms or group of atoms."
