Answer
The lewis structure is shown in the picture.
Work Step by Step
1) Draw the atoms connected to each other in the sequence the structural formula is given.
2) Count the number of valence electrons involved in the bonding, which is 10. There should be 1+1+1+4+4+5 = 16. So make two more bonds between C and N.
3) Now there are 14e.
4) Since N has already made three bonds. Place the remaining electrons as lone pairs on the N
4) Now count the valence electrons, it should be 16e.
