Rajasthan BoardEnglish MediumSTD 11 ScienceChemistry4. Chemical bonding and molecular structure1 Mark
MCQ
Assertion : $SeCl_4$ does not have a tetrahedral structure.
Reason : $Se$ in $SeCl_4$ has two lone pairs.
  • A
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • B
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • ✓
    If the Assertion is correct but Reason is incorrect.
  • D
    If both the Assertion and Reason are incorrect.
✓

Answer

Correct option: C.
If the Assertion is correct but Reason is incorrect.
c
$SeCl_4$ has distorted trigonal pyramidal geometry; here $Se$ has only one lone pair of electrons hence it has $sp^3d$ hybridisation.
