`AICI_(3)` is covalent while `AIF_(3)` is ionic This can be justified on the basic of .

Assertion: Anhydrous AlCl_(3) is covalent while hydrated AlCl_(3) is ionic. Reason: In water AlCl_(3) is presennt as Al_((aq.))^(3+) and Cl_((aq.))^(-) ion.

AlCl_3 anhydrous is covalent but AlCl_3. 6H_2O is ionic because

Al_(4)C_(3) is a ionic carbide, named as:

Al_(4)C_(3) is a ionic carbide, named as:

BI_(3) is an ionic compound. True or false

Hydride of Be is Covalent while that of Na is ionic Why ?

Explain why NH_(3) is basic while BiH_(3) is only feebly basic ?

Anhydrous AlCl_(3) is covalent however, when it is dissolved in water hydrated ionic species are formed. This transformation is owing to:

Fill in the blanks by chossing the appropriate word/words from those given in the brackets: (increases, ionic radius, CH_(2) , same, sigma, ionic, 14, 2, decreases, 16, CH_(3) , pi, covalent, ionic) The carbon-carbon triple bond in acetylene comprises of one _____ and two ______bonds.

Preduct that anhyrous AICI_(3) is covalent form the data given below, ionisation enegry for AI = 5137 kJ mol^(-1), Delta_(hyd) H for AI^(3+) =- 4665 kJ "mole"^(-1), Delta_(hyd)H for CI^(Theta) =- 381 kJ mol^(-1))
