Chemical Bonding and Atomic Structure MCQs for NEET — Chemistry Questions with Answers

(b) $K{O}_2$ is an ionic compound

(b) only P has d-orbitals. 

(d) (a) ${\mathrm{H}}_2....{\mathrm{H}}_2\mathrm{O}$               Dipole-induced dipole interaction (van der Waal's force) energy<8kJ/mol

(b) $\mathrm{H}—\mathrm{Cl}.....\mathrm{H}—\mathrm{CI}$         Dipole-dipole interaction (van der Waal's force)<8kJ/mol

(c) ${\mathrm{H}}_{2}0.....\mathrm{HF}$                      H-bond 

(d) all                

(d) In ${\mathrm{CDI}}_2$, Pink colour is due to polarization of ${\mathrm{I}}^{-} \mathrm{by} {\mathrm{Cd}}^{2+}$ has pseudo noble gas configuration. In ${\mathrm{CdCI}}_2$, extent of polarization of ${\mathrm{Cl}}^{- }\mathrm{by} {\mathrm{Cd}}^{2+}$ is relatively less, hence specific colour cannot be predicted.

(b)I3 + has a bent shape which is sp3 hybridized. The central atom iodine atom has 6 electrons because of one positive charge, it will make single bonds with 2 I atoms to complete their and it`s own octet, keeping the loan pair upside we get a bent shape.

(b) Due to $s{p}^2$- hybridization.

(c) Carbon cannot accept $6C{l}^{-}$, since it has no vacant d-orbitals. 

(d) $Cl{O}_2$ has 33 electrons ; one will be unpaired 

(a) more is the dipole moment more is ionic nature. $\mu =\delta \times d;$ higher is $\mu$, more will be $\delta$ on that atom.
