Question

Q32. A metal 'X' combines with a non-metal 'Y' by the transfer of electrons to form a
compound Z.(3)
(i) State the type of bond in compound 'Z'.
(ii) What can you say about the melting point and boiling point of compound Z?
(iii) Will this compound be a good conductor of electricity?​

Answer 1

Answer:

Let ,

the metal compound 'X' is 'Na' (sodium)

the non metal compound 'Y' is 'Cl2' (chlorine)

2Na + cl2 = 2Nacl

(i) The compound 'Z' is Nacl

the compound 'Z' is a type of ionic bond

because it is the bond between the

electronegative and electropositive element

(ii) It has high melting and boiling point because ionic compound has high melting point because of intermolecular forces of attraction.

(iii) It is also good conductor of electricity because ionic compound are good conductor of electricity.

Hope this will help you!!
