N-methylbutan-2-amine
Work Step by Step
The longest continuous chain of four carbon determines the butane. The -e ending in the alkane name is changed to -amine, and 2 is the position of the amino group along the chain. Other substituents on the carbon chain are given numbers, and the prefix N- is used for each substituent on nitrogen. Since there is one methyl, its N-methylbutan-2-amine.
