Which of the following bonds tend to have the most intense signal in an IR spectrum.Select answer from the options belowCsp2—H C=C C ≡≡ CC=O

The bond that tends to have the most intense signal in an IR spectrum is C=O.

Here's why:

1. The intensity of an IR signal depends on the change in dipole moment that occurs during a vibration. The greater the change in dipole moment, the more intense the signal.

2. C=O bonds have a significant difference in electronegativity between the carbon and oxygen atoms, leading to a large dipole moment.

3. In contrast, Csp2—H, C=C, and C≡≡C bonds have less of a difference in electronegativity between the bonded atoms, resulting in smaller dipole moments.

4. Therefore, C=O bonds tend to produce the most intense signals in an IR spectrum.
