Which of the following statements are correct? 1 . A σ bond is stronger than a π bond 2 . A covalent bond is stronger than a hydrrogen bond 3 . HF is more polar than HCl 4 . There is one electrovalent bond and three covalent bonds in methylene chloride Select the correct answer using the codes given below

Options

  1. A2, 3 and 4
  2. B1 and 3
  3. C1, 2 and 4
  4. D1, 2 and 3

Correct answer

D. 1, 2 and 3

Step-by-step solution

Here statement 1, 2 and 3 are correct while 4 is incorrect as in methylene chloride C H 2 C l 2 , all four bonds are covalent. A σ and covalent bond are stronger than a π bond due to stronger overlapping. HF is more polar than HCl due to more electronegativity difference.
