               Objective-
               MCQs
              Q.1      Which combination of atoms is most likely to produce a compound with ionic
                       bonds?
                       (a). Al and F (b). P and H (c). C and O (d). Si and O
              Q.2      An element reacts with oxygen to give a compound with a high melting point. This
                       compound is soluble in water. The element is likely to be-
                         (a) calcium                       (b) carbon
                         (c) silicon                       (d) iron
              Q.3      Which of the following property is not of ionic compound?
                       (a) Solubility in water                              (b) High melting and boiling points
                       (c). Electrical conductivity in solid state  (d) Electrical conductivity in molten state
                 ➢  For Assertion& Reason question follow the following directions.

              DIRECTION:   Each of these questions contains an Assertion followed by Reason. Read
              them carefully and answer the question on the basis of following options. You have to
              select the one that best describes the two statements.
              (a) If both Assertion and Reason are correct and Reason is the correct explanation of
              Assertion.
              (b) If both Assertion and Reason are correct, but Reason is not the correct explanation of
              Assertion.

              (c) If Assertion is correct but Reason is incorrect.
              (d) If Assertion is incorrect but Reason is correct.

              (e) If Assertion & Reason both are incorrect.

              Q.4      Assertion A : Na and Cl form ionic bond.
                       Reason  R :  Large ionization metal and big non-metal form ionic bonds

              Q.5
                       Assertion:-  Ionic  compounds  exhibits  electrical  conductivity  in  solution  state.
                       Reason :- In solution state electrons of ionic compounds are free.
