Increasing order of carbon-carbon bond length for the following is

Options

  1. AC < B < A < D
  2. BB < C < A < D
  3. CD < C < A < B
  4. DB < A < C < D

Correct answer

D. B < A < C < D

Step-by-step solution

In C ₂ H ₆ , carbon-carbon bond is single (1.54 А). In C ₆ H ₆ , carbon-carbon bond is partially double (1.39 A) In C ₂ H ₄ , carbon-carbon bond is double (1.34 Å) In C ₂ H ₂ , carbon-carbon bond is triple (1.10 Å)
