Refer to Animation: Kinetic and Potential Energy. Which of the factors accounts for the higher potential energy of C-C and C-H b
onds compared to C-O and H-O bonds? A) The C-C and C-H bonds are strong, thus requiring a lot of energy to hold together.
B) The CO and H-O bonds are weak, thus requiring less energy to hold together.
C) The C-C and C-H bonds are weak, thus requiring a lot of energy to hold together.
D) The CO and wo bonds are strong, thus requiring a lot of energy to hold together.
The electronegativity difference in C-C and C-H atoms is quite low. This means smaller the electron cloud. This further means larger bond length that is electron's are further from the nucleus. hence, higher potential energy of C-C and C-H bonds.
On the contrary, C-O and H-O have large difference in electronegativity( O is high electronegative element) . This means smaller bond length. Electron's near the nucleus. Thus, lower potential energy of bonds.
Explanation: the number of circles in the electronic configuration of an element is represented in the periodic table as the period number that element is situated in. the number of electrons in the outermost shell of an element is represented in the periodic table as the group number that element is situated in.
