The lewis structure is shown in the diagram attached. The hybridization is from the left: $C_1$: $sp^3$ $C_2$: $sp^2$ $N$: $sp^2$ $C_3$: $sp^3$
Work Step by Step
Draw the lewis structure the way the molecular formula is shown. For $C_1$ and $C_3$ there are four domains so $sp^3$. For $N$ is there are three domains, so the hybridization is $sp^2$.
