Which of the following statements is false?

Options

  1. AHCl molecule has one sigma bond
  2. BAcetylene molecule has three pi bonds and three sigma bonds
  3. CEthylene molecule has five sigma bonds and one pi bond
  4. DWater molecule has two sigma bonds and two lone pairs

Correct answer

B. Acetylene molecule has three pi bonds and three sigma bonds

Step-by-step solution

Here Acetylene molecule has 3 σ bonds and 2 π bonds. H-Cl has only one sigma bond so it is correct. In water there are 2 sigma bond and 2 lp electrons so it is also correct. Ethylene has also 5 sigma and one pi bonds so it is also correct.
