CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE
313887
Assertion : \(\mathrm{CHCl}_{3}\) and \(\mathrm{CH}_{3} \mathrm{OH}\) are miscible. Reason : One of them is polar.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
\(\mathrm{CHCl}_{3}\) and \(\mathrm{CH}_{3} \mathrm{OH}\) are indeed miscible in each other primarily due to the presence of intermolecular van der Waals' forces of attraction. Both of these compounds are polar molecules. So the option (3) is correct.

Identify metal halide from the following having highest ionic character? \((\mathrm{M}=\) metal atom)
1 \(\mathrm{MF}\)
2 \(\mathrm{MBr}\)
3 \(\mathrm{MI}\)
4 \(\mathrm{MCl}\)
Explanation:
Ionic character of metal halides decreases in the order : \(\mathrm{MF}>\mathrm{MCl}>\mathrm{MBr}>\mathrm{MI}\)

Which of the following molecules is non-polar in nature ?
1 \({\rm{C}}{{\rm{H}}_{\rm{2}}}{\rm{O}}\)
2 \({\rm{SbC}}{{\rm{l}}_{\rm{5}}}\)
3 \({\rm{N}}{{\rm{O}}_{\rm{2}}}\)
4 \({\rm{POC}}{{\rm{l}}_{\rm{3}}}\)
Explanation:
\({\rm{SbC}}{{\rm{l}}_{\rm{5}}}\) is non-polar Hybridisation of Sb in \({\rm{SbC}}{{\rm{l}}_{\rm{5}}}\,\,{\rm{is}}\,\,{\rm{s}}{{\rm{p}}^{\rm{3}}}{\rm{d}}\) &emps; I I I Geometry \( \Rightarrow \) Trigonal bipyramidal which is symmetrical geometry so dipole moment is zero. So it is non-polar.

CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

Assertion : According to Fajan's rule, covalent character is favoured by small cation and large anion. Reason : The magnitude of covalent character in the ionic bond depends upon the extent of polarisation.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Fajan's rules states that a smaller cation and a larger anion, along with a higher charge on the cation, increase the covalent character of an ionic bond by enhancing polarisation, resulting in greater electron charge buildup between nuclei and a higher percentage of covalent character. So the option (1) is correct.
