In acetylene molecule, between the carbon atoms there are

• A

  three $\sigma$-bonds
• B

  two $\sigma$ and one $\pi$-bonds
• Correct answer
  C

  one $\sigma$ and two $\pi$-bonds
• D

  three $\pi$-bonds

Solution

In acetylene, between carbon atoms, there are one $\sigma$ and two f-bonds i.e.

Hence, the correct answer is option: 'C'.
