What bond distance is expected to be longest? 1. A carbon-carbon bond with a bond order of 2 2. A carbon-carbon bond with a bond order of 3 3. A carbon-carbon bond with a bond order of O 4. carbon-carbon bond with a bond order of 1
Bond length of C=C is largest(134 pm) because both the carbon atoms have same electronegativity. In case of C=O. and C=N carbon is bonded to highly electronegative atoms so bond length is shoreter as compared to C=C
