Among the following, which one is a WRONG statement?

Options

  1. AI 3 + has bent geometry
  2. BPH 5  and  BiCl 5 do not exist
  3. Cpπ - dπ bonds are present in SO 2
  4. DSeF 4  and  CH 4 have same shape

Correct answer

D. SeF 4  and  CH 4 have same shape

Step-by-step solution

The incorrect statement about the structure is SeF 4 and CH 4 because it is containing a different structure, based on outer shell electronic configuration. In SeF 4 , selenium contains 6 e - in outermost shell and forms 4 bonds with fluorine atom and 2 e - is still in vacant hybridised orbital to form 4 bp + 1 lp configuration. And in CH 4 , the carbon atom has 4 e - in outermost shell electronic configuration and four hydrogen atoms attached to a carbon atom to form tetrahedral structure.
