CHXI11:THE P-BLOCK ELEMENTS

316489 Assertion :
The stability order of +1 oxidation state of Ga , In and Tl is \({\mathrm{\mathrm{\mathrm{Ga} < \mathrm{In} < \mathrm{Tl}}}}\).
Reason :
The inert pair effect stabilizes the lower oxidation state down the group.

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.

CHXI11:THE P-BLOCK ELEMENTS

316490 Which of the following ion does not exist?

1 \(\mathrm{B}^{3+}\)
2 \(\mathrm{Al}^{3+}\)
3 \(\mathrm{Ga}^{3+}\)
4 \(\mathrm{In}^{3+}\)
CHXI11:THE P-BLOCK ELEMENTS

316509 \(\mathrm{C}\) and \(\mathrm{Si}\) belong to IV group or gp. 14. The maximum co-ordination number of carbon in commonly occuring compounds is 4 , whereas that of silicon is 6. This is due to :

1 Large size of silicon
2 Availability of vacant d-orbitals in silicon
3 More electropositive nature of silicon
4 Silicon being vulnerable to attack by nucleophilic reagents.
CHXI11:THE P-BLOCK ELEMENTS

316510 Carbon has no tendency to form complex compounds because of

1 Its small size
2 The availability of vacant d-orbitals
3 Non availability of vacant d-orbitals
4 No tendency to form covalent bonds
CHXI11:THE P-BLOCK ELEMENTS

316511 Read the Statement -A and Statement -B carefully to mark the correct options given below:
Statement A :
From silicon to Pb , there is small increase in radius due to the presence of completely filled d- and f-subshells in heavier elements.
Statement B :
From carbon to Si there is considerable increase in radius.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
