Question

which bond is the strongest?

Explanation:

• Bond Types and Strength:
• In organic chemistry, the strength of carbon - carbon bonds is related to the type of bond. A single bond (like in bond A) is formed by a sigma ($\sigma$) bond. A double bond (bond B) consists of one $\sigma$ bond and one pi ($\pi$) bond. A triple bond (bond C) is composed of one $\sigma$ bond and two $\pi$ bonds.
• The more bonds between two atoms (in terms of the number of electron - sharing interactions), the stronger the overall bond. Triple bonds have more electron density between the two carbon atoms compared to double and single bonds. This increased electron - sharing results in a stronger electrostatic attraction between the positively charged carbon nuclei and the negatively charged electrons in the bonds.

Answer:

C
