C₃H₃NOS,
Number of valence electron of carbon: 4
Number of valence electron of hydrogen : 1
Number of valence electron of nitrogen: 5
Number of valence electron of sulfur: 6
Total number of valence electrons in C₃H₃NOS
=no. of carbon atoms×4+1×no. Of hydrogen atom+5×no. of nitrogen atom+6×no. of oxygen atom +6×no. of sulfur atom
=3×4+1×3+5×1+6+6
=12+3+5+6+6
=32
So, total number of valence electrons in C₃H₃NOS is 32.
