MCQ
All the following $IUPAC$ names are correct except :
- A$1-$ chloro $-1-$ ethoxy propane
- ✓$1-$ amino $-1-$ ethoxypropane
- C$1-$ ethoxy $-2-$ propanol
- D$1-$ ethoxy $-1-$ propanamine
✓
Answer
Correct option: B.
$1-$ amino $-1-$ ethoxypropane
b
The structure of $1$ - Chloro-$1$-ethoxy - propane will be: $CH _3 CH _2 CH \text { (Cl) } OCH _2 CH _3$
The structure of $1$ - Chloro-$1$-ethoxy - propane will be: $CH _3 CH _2 CH \text { (Cl) } OCH _2 CH _3$
The structure of $1$ - Ethoxy - $2$ - propanol will be: $CH _3 CH \text { (OH) } CH _2 OCH _2 CH _3$
The structure of $1$ - Amino -$1$ - ethoxy - propane will be: $CH _3 CH _2 CH \left( NH _2\right) OCH _2 CH _3$
But the IUPAC name $1$ - Amino - $1$ - ethoxy - propane is incorrect as amino group has higher priority than ethoxy group.
So, all of the IUPAC names are correct except $1$ - Amino-$1$-ethoxy -propane.
