CHXI11:THE P-BLOCK ELEMENTS

316506 Which is not a characteristic property of carbon?

1 Catenation
2 Multiple bond formation
3 Availability of d-orbitals for bonding
4 Highest electronegativity in the group.
CHXI11:THE P-BLOCK ELEMENTS

316507 Carbon, the first member of group 14 , shows an anomalous behaviour because of
(I) Its exceptionally small atomic and ionic size
(II) Its higher electronegativity
(III) Its higher ionization enthalpy
(IV) The absence of vacant d- orbitals in the valence shell

1 (I), (II)
2 (II), (III)
3 (III), (IV)
4 (I), (II), (III), (IV)
CHXI11:THE P-BLOCK ELEMENTS

316508 Assertion :
Carbon forms large number of stable compounds
Reason :
Carbon is less electronegative as compared to other members of group 14.

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.
