190067 Given below are two statements: one is labelled as Assertion \((A)\) and the other is labelled as Reason \((R)\)Assertion \((A)\) : Boron is unable to form \(BF _{6}^{3-}\)Reason \((R)\) : Size of \(B\) is very small.In the light of the above statements, choose the correct answer from the options given below.

1 Both \((A)\) and \((R)\) are true and \((R)\) is the correct explanation of \((A)\)
2 Both \((A)\) and \((R)\) are true but \((R)\) is not the correct explanation of \((A)\)
3 \((A)\) is true but \((R)\) is false
4 \((A)\) is false but \((R)\) is true

189653 Aluminium is more reactive than iron. But aluminium is less easily corroded than iron because

1 Aluminium is a noble metal
2 Oxygen forms a protective oxide layer
3 Iron undergoes reaction easily with water
4 Iron forms mono and divalent ions
11. THE P-BLOCK ELEMENTS

189654 Aluminium vessels should not be washed with materials containing washing soda since

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

189655 Which of the statements about anhydrous aluminium chloride is correct

1 It exists as \(AlC{l_3}\) molecule
2 It is not easily hydrolysed
3 It sublimes at \({100\,^o}C\) under vacuum
4 It is a strong Lewis base
