Question

All the following $IUPAC$ names are correct except:

• A. $1$ -Chloro- $1$ -ethoxypropane
• B. $1$ -Amino- $1$ -ethoxypropane
• C. $1$ -Ethoxy- $2$ -propanol
• D. $1$ -Ethoxy- $1$ -propanamine

Answer 1

Answer: (B)

All the given IUPAC names are correct except $1-$ amino $-1-$ ethoxypropane. As the highest priority functional group in this compound is amine, it will be the suffix. Parent carbon chain is a three carbon chain, and $-OC_{2}H_{5}$ is a substituent for which 'ethoxy' is the prefix. So, $IUPAC$ name of the compound is $1-$ ethoxypropan $-1-$ amine.
