  • Question 1
    4 / -1

    Among the following the maximum covalent character is shown by the compound

    Solution

    Higher the positive oxidation state higher will be the covalent character.

    Hence, option C is correct.

  • Question 2
    4 / -1

    Which of the following compounds is not an antacid?

    Solution

    Phenelzine is tranquilizer. It is not an antacid.

    Hence, option C is correct

  • Question 3
    4 / -1

    The ionic radii (in Å) of N3-, O2- and F- are respectively :

    Solution

    These are isoelectronic species as the number of electrons present in all species = 10 electrons.
    As negative charge increases,size of the ions increases and ionic radius increases. 
    Hence, option C is correct.

  • Question 4
    4 / -1

    Which of the following facts about the complex [Cr(NH3)6]Cl3 is wrong?

    Solution

    It is an inner orbital complex as the d-orbital involved in hybridization belongs to penultimate shell. 
    Hence, option C is correct.

  • Question 5
    4 / -1

    Assertion : Nitrogen and Oxygen are the main components in the atmosphere but these do not react to form oxides of nitrogen. 
    Reason : The reaction between nitrogen and oxygen requires high temperature.

    Solution

    Assertion is true because it is an observation that nitrogen being highly stable does not react with oxygen in atmosphere. 
    The reaction to form oxides of nitrogen takes place at higher temperature (≈ 2000 K). 
    So, reason is correct and also the correct explanation of the assertion. 
    Hence, option A is correct

  • Question 6
    4 / -1

    In the context of the Hall-Heroult process for the extraction of Al, which of the following statements is false?

    Solution

    (1) In this process, carbon anode is oxidised to CO and CO2. 
    (2) It is a fact 
    (3) At cathode, Al3+ from Al2O3 is reduced to Al. 
    (4) Al2O3 is the electrolyte, which is undergoing the redox process. So, Al2O3 serves as electrolyte and Na3AIF6, although an electrolyte, serves as solvent. 
    Hence, option D is correct

  • Question 7
    4 / -1

    The organic chloro compound, which shows complete stereochemical inversion during a SN2 reaction, is

    Solution

    CH3Cl is a primary halo alkane and therefore will have a back side attack.
