Which of the following species contains equal number of σ\sigma - and π\pi - bonds?Which of the following species contains equal number of σ - and π - bonds?Which of the following species contains equal number of σ - and π - bonds?Which of the following species contains equal number of σ - and π - bonds?Which of the following species contains equal number of σ - and π - bonds?

Options

  1. AHCO3−{HCO}_{3}^{-}
  2. BXeO4Xe{O}_{4}
  3. C{\left(CN\right)}_{2}
  4. DC{H}_{2}{\left(CN\right)}_{2}

Correct answer

B. XeO4Xe{O}_{4}

Step-by-step solution

Given below are the structures of the molecules given in the options.

Which of the following species contains equal number of σ - and π - bonds? =4σ,1π= 4\sigma, 1\pi bond

Which of the following species contains equal number of σ - and π - bonds? =4σ,4π= 4\sigma, 4\pi bond

Which of the following species contains equal number of σ - and π - bonds?=3σ,4π= 3\sigma, 4\pi

Which of the following species contains equal number of σ - and π - bonds?=6σ,4π= 6\sigma, 4\pi bond

Hence, XeO4 contains equal number of sigma and pi bonds.

(Double bond contains one sigma and one pi bond and triple bond contains one sigma and 2 pi bonds).
