Refer to animation: kinetic and potential energy. which of the factors accounts for the higher potential energy of c-c and c-h bonds 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.

Explanation:

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.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

idk what the question is about
