A C-O Single Bond Is 143 Pm in Length,whereas an O-O

Multiple Choice

A C-O single bond is 143 pm in length,whereas an O-O single bond is 148 pm in length. Which bond is weaker and why?

A) The C-O bond is weaker because O is more electronegative than C.
B) The C-O bond is weaker because each O atom is electronegative and pulls the shared electrons toward itself.
C) The O-O bond is weaker because oxygen has d orbitals to engage in bonding.
D) The C-O bond is weaker because C is more electronegative than O.
E) The O-O bond is weaker because both oxygens are equally electronegative and pull the shared electrons toward themselves.
