Question
Consider the trends in atomic radii on the periodic table. The bond in citrate that is the longest and weakest with the lowest bond dissociation energy is the:A.C–H bond.B.C=O bond.C.C–C bond.D.The bond length and strength cannot be determined without more information.
Solution
The bond length and strength in a molecule are determined by the types of atoms involved and the nature of the bond between them.
A. C-H bond: Carbon and hydrogen form a single bond. This bond is relatively short and strong due to the small size of the hydrogen atom.
B. C=O bond: Carbon and oxygen form a double bond. Double bonds are generally shorter and stronger than single bonds because they involve more shared electrons.
C. C-C bond: Carbon atoms can form single bonds with each other. These bonds are typically longer and weaker than C-H and C=O bonds.
Therefore, the C-C bond is likely to be the longest and weakest bond in citrate, with the lowest bond dissociation energy. So, the answer is C. C-C bond.
