Gujarat BoardEnglish MediumSTD 11 ScienceChemistry4. Chemical bonding and molecular structure1 Mark
MCQ
Predict the correct order among the following :
  • A
    bond pair $-$ bond pair $>$ lone pair $-$ bond pair $>$ lone pair $-$ lone pair
  • B
    lone pair $-$ bond pair $>$ bond pair $-$ bond pair $>$ lone pair $-$ lone pair
  • ✓
    lone pair $-$ lone pair $>$ lone pair $-$ bond pair $>$ bond pair $-$ bond pair
  • D
    lone pair $-$ lone pair $>$ bond pair $-$ bond pair $>$ lone pair $-$ bond pair
✓

Answer

Correct option: C.
lone pair $-$ lone pair $>$ lone pair $-$ bond pair $>$ bond pair $-$ bond pair
c
According to $V.S.E.P.R.$ Theory lone-lone pair repulsion is maximum because lone pair electron held by nuclei of one atom there for occupy more space. Repulsion $\Rightarrow$ lone pair-lone pair $>$ lone pair-bond pair $>$ bond pair-bond pair
