Given below are two statements : Statement (I) : The first...
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 the corresponding elements of group 14. In the light of the above statements, choose the most appropriate answer from the options given below :
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 the corresponding elements of group 14. In the light of the above statements, choose the most appropriate answer from the options given below :
Options
- AStatement I is correct but Statement II is incorrect
- BStatement I is incorrect but Statement II is correct
- CBoth Statement I and Statement II are incorrect
- DBoth Statement I and Statement II are correct
Correct answer
A. Statement I is correct but Statement II is incorrect
Step-by-step solution
Statement 1 is correct since left to right increases in general in periodic table.
Statement 2 is incorrect since M.P. of group 14 elements is more than group 13 elements.
Statement 2 is incorrect since M.P. of group 14 elements is more than group 13 elements.
