Solution


Q.

Given below are two statements :

Statement I : C < O < N < F is the correct order in terms of first ionization enthalpy values.

Statement II : S > Se > Te > Po > O is the correct order in terms of the magnitude of electron gain enthalpy values.

In the light of the above statements, choose the correct answer from the options given below :              [2026]
1 Both Statement I and Statement II are false  
2 Both Statement I and Statement II are true  
3 Statement I is false but Statement II is true
