[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
Which of the following is TRUE when comparing a C-C bond and and an O-O bond?
|
|
The O-O bond length will be shorter due to the increased radii of the oxygen atoms compared to C atoms
|
|
|
The O-O bond will be weaker due to the increased radii of the O atoms compared to the C atoms
|
|
|
Both bonds would be the same length because both S and O are in the same period
|
|
|
The O-O bond would be stronger because C atoms have a larger radii than O atoms
|
Explanation:
Detailed explanation-1: -Solution : The bond energies of F-F, C-C, N-N and O-O bonds are 33, 80, 39 and 34.2 kJ/mole respectively. Therefore molecule of C-C has the highest bond energy .
Detailed explanation-2: -In the C-C complex. one single bond is present between the two carbon atoms and in the C=C, there is a double bond present. The double bond is made up of one sigma and one pi bond, which create a stronger bond between the two atoms. Therefore, the C=C bond is stronger.
Detailed explanation-3: -It’s stronger because of a dipole moment. oxygen is more electronegative than carbon, so there is a stronger attraction between C and O than a C=C bond.
