Which bond is stronger c-h or o-h

Since the bond with most electronegativity difference would be the strongest, it would be the O-H bond.

Which bond is stronger between CH and O-H?

According to this this table (PDF) the bond dissociation energy (BDE) of OH is 460 kJ/mol (110 kcal/mol) and the value for CH is 389 kJ/mol (93 kcal/mol).

Why are O-H bonds more acidic than C-H bonds?

Oxygen, with a higher electron affinity, generally forms more stable anion than does carbon. An O-H bond is thus more acidic than a C-H bond.

How strong is an O-H bond?

For example the average bond energy of O-H in H₂O is 464 kJ/mol. This is due to the fact that the H-OH bond requires 498.7 kJ/mol to dissociate, while the O-H bond needs 428 kJ/mol.

Is C-H bond the strongest?

Although the C−H bond is one of the strongest, it varies over 30% in magnitude for fairly stable organic compounds, even in the absence of heteroatoms.
