Given below are two statements : In the light of the above statements, choose the correct answer from the options given below

  1. Statement I is true but Statement II is false
  2. Statement I is false but Statement II is true
  3. Both Statement I and Statement II are true
  4. Both Statement I and Statement II are false

Answer

(4) Both Statement I and Statement II are false

Solution

Statement I: The H–X bond length increases from HF to HI because the size of X increases. The longest bond is H–I, and iodine has the largest (not the smallest) covalent radius in group 17. Statement I is false.

Statement II: Boiling points: PH3 < AsH3 < NH3 < SbH3 < BiH3

(NH3 is raised by hydrogen bonding) the lowest boiling hydride is PH3 E = P.

As per NCERT, P can expand its covalency beyond 4 using vacant 3d orbitals (e.g. PCl5, [PF6]-); only nitrogen is limited to a maximum covalency of 4.

Statement II is false.

Answer: (4)
