316908 Which gas is liberated when \({\text{A}}{{\text{l}}_{\text{4}}}{{\text{C}}_{\text{3}}}\) is hydrolysed?

1 \(\mathrm{CH}_{4}\)
2 \(\mathrm{C}_{2} \mathrm{H}_{2}\)
3 \(\mathrm{C}_{2} \mathrm{H}_{6}\)
4 \(\mathrm{CO}_{2}\)
CHXI11:THE P-BLOCK ELEMENTS

316907 \(\mathrm{AlCl}_{3}\) is more volatile than \(\mathrm{NaCl}\); this is because

1 the \(\mathrm{AlCl}_{3}\) molecules are held by weak van der Waals forces, whereas in \(\mathrm{NaCl}\), the \(\mathrm{Na}^{+}\) and \(\mathrm{Cl}^{-}\)ions are held by strong ionic forces
2 unlike \(\mathrm{NaCl}, \mathrm{AlCl}_{3}\) is dimerised
3 sodium is more electropositive than aluminium
4 \(\mathrm{NaCl}\) is a natural product.
CHXI11:THE P-BLOCK ELEMENTS

316895 \({\text{Al + }}{{\text{N}}_{\text{2}}} \to {\text{A}}\)
\({\text{Al + C}} \to {\text{B}}\)
Product A and B on hydrolysis yields, respectively.

1 Ammonia and acetylene
2 Ammonia and methane
3 Nitric oxide and acetylene
4 Nitric oxide and methane
CHXI11:THE P-BLOCK ELEMENTS

316896 Assertion :
\(\mathrm{Al}(\mathrm{OH})_{3}\) is amphoteric in nature.
Reason :
Al-O and O-H bonds can be broken with equal ease in \(\mathrm{Al}(\mathrm{OH})_{3}\).

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.

316897 Aluminium vessels should not be washed with materials containing washing soda because -

1 Washing soda is expensive
2 Washing soda is easily decomposed
3 Washing soda reacts with aluminium to form soluble aluminate
4 Washing soda reacts with aluminium to form insoluble aluminium oxide
