We’re being asked to determine the number of σ and π bonds in C3H4.
Carbon is the internal atom
Group Valence Electrons
C 4A 3 × 4 e– = 12 e–
H 1A 4 × 1 e– = 4 e–
Total: 18 valence e–
Draw the Lewis structure for the molecule C3H4. How many sigma and pi bonds does it contain?
a) 8 sigma, 2 pi
b) 10 sigma, 2 pi
c) 6 sigma, 2 pi
d) 8 sigma, 0 pi
e0 7 sigma, 0 pi
