CHXI11:THE P-BLOCK ELEMENTS

316299 The difference in properties of \(\mathrm{CH}_{4}\) and \(\mathrm{SiH}_{4}\) is due to

1 large difference in the electronegativity of carbon and silicon
2 large difference in size of \(\mathrm{C}\) and \(\mathrm{Si}\) atoms
3 the inability of carbon to expand its octet
4 the inability of silicon to form double bonds

CHXI11:THE P-BLOCK ELEMENTS

316301 Given below are two statements one is labelled as (A) and the other is labelled as Reason \({\rm{(R)}}\).
Assertion :
All MX \({ }_{4}\) of 14th group except \(\mathrm{CX}_{4}\), are easily hydrolyzed by water.
Reason :
In cases other than carbon, the central atom of \(\mathrm{MX}_{4}\) has d-subshell to
accommodate lone pair of electrons from O atom of \(\mathrm{H}_{2} \mathrm{O}\).

In the light of the above statements, choose the most appropriate answer from the options given below:

1 Both Assertion and Reason are true and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and is reason incorrect.
