Given below are two statements: Statement (I) : The first ionisation enthalpy of group 14 elements is higher than the corresponding elements of group 13. Statement (II) : Melting points and boiling points of group 13 elements are in general much higher than those of corresponding elements of group 14. In the light of the above statements, choose the most appropriate Answer from the options given below:

Answer: (3)

Solution

Ionisation energy increases left to right, so Statement I is correct (group 14 > group 13). Melting/boiling points also
