We’re being asked to determine the number of σ and π bonds in (CH3)2CO.
Carbon is the internal atom
Group Valence Electrons
C 4A 3 × 4 e– = 12 e–
O 6A 1 × 6 e– = 6 e–
H 1A 6 × 1 e– = 6 e–
Total: 24 valence e–
How many sigma (σ) and pi (π) bonds are in a molecule of acetone, (CH3)2CO?
a) 9 σ, 2 π
b) 8 σ, 1 π
c) 8 σ, 2 π
d) 9 σ, 1 π
e) 10 σ, 0 π
