Question

Which of the following functional groups always has non-zero formal charges in its Lewis structure?

A. -oh

B. -No2

C.-Nh2

D. -co2h

2. What is the condensed structure for butane?

3. Resonance is the result of

A. Side to side overlap of p orbitals

B. End to end overlap of p orbitals

C. End to end overlap of s orbitals

D. Side to side overlap of d orbitals

Answer 1

1.Formal charge = [# of valence electrons] – [electrons in lone pairs + 1/2 the number of bonding electrons]

NO₂ = 5 -( 0 + 1/2*4 =1 )

2.CH₃CH₂CH₂CH₃

3. A. Side to side overlap of p orbitals
