Answer: The structural formula can be represented as:
Step-by-step explanation:
The question requires us to draw the structural formula for the compound CH3CH2CH(NH2)CH3.
The structural formula of a molecule gives us the location and type (simple, double or triple) of chemical bonds in the molecule.
To draw the structural formula of an organic compound, we must pay attention to the maximum number of bonds that carbon can make (4 bonds total) and place the atoms accordingly.
Considering the information above, the structural formula of the compound CH3CH2CH(NH2)CH3 can be represented as:
(In the image, the structural formula of the molecule is represented in black and below it, in blue, a similar representation to what was given by the question).
Note that all carbons represented are making a total of bonds and the heterogeneous group (NH2) is also bonded to a carbon in the main chain.
