Q2.

Given below are two statements:

Statement I: Aluminium is more electropositive than thallium as the standard electrode potential value of $E^{\circ}_{\text{Al}^{3+}/\text{Al}}$ is negative and $E^{\circ}_{\text{Tl}^{3+}/\text{Tl}}$ is positive.

Statement II: The sum of first three ionization enthalpies of boron is very high when compared to that of aluminium. Due to this reason boron forms covalent compounds only and aluminium forms $\text{Al}^{3+}$ ion.

In the light of the above statements, choose the correct answer from the options given below

(A)

Both Statement I and Statement II are true

(B)

Both Statement I and Statement II are false

(C)

Statement I is true but Statement II is false

(D)

Statement I is false but Statement II is true
