JEE MAIN - Chemistry (2024 - 9th April Evening Shift - No. 11)
Match List I with List II
| LIST I | LIST II | ||
|---|---|---|---|
| A. | Melting Point $$[\mathrm{K}]$$ | I. | $$\mathrm{T} 1>\mathrm{In}>\mathrm{Ga}>\mathrm{A} 1>\mathrm{B}$$ |
| B. | Ionic Radius $$[\mathrm{M}^{+3} / \mathrm{pm}]$$ | II. | $$\mathrm{B}>\mathrm{T} 1>\mathrm{Al} \approx \mathrm{Ga}>\mathrm{In}$$ |
| C. | $$\Delta_{\mathrm{i}} \mathrm{H}_1[\mathrm{~kJ} \mathrm{~mol}^{-1}]$$ | III. | $$\mathrm{T} 1>\mathrm{In}>\mathrm{Al}>\mathrm{Ga}>\mathrm{B}$$ |
| D. | Atomic Radius [pm] | IV. | $$\mathrm{B}>\mathrm{A} 1>\mathrm{T} 1>\mathrm{In}>\mathrm{Ga}$$ |
Choose the correct answer from the options given below:
A-IV, B-I, C-II, D-III
A-I, B-II, C-III, D-IV
A-III, B-IV, C-I, D-II
A-II, B-III, C-IV, D-I
Explanation
Melting point : $$\mathrm{B}>\mathrm{A} \ell>\mathrm{T} \ell>\mathrm{In}>\mathrm{Ga}$$
Ionic radius $$(\mathrm{M}^{+3} / \mathrm{pm}): \mathrm{T} \ell>\mathrm{In}>\mathrm{Ga}>\mathrm{A} \ell>\mathrm{B}$$
$$\left(\Delta_{\mathrm{IE}} \mathrm{H}\right)_1\left[\frac{\mathrm{kJ}}{\mathrm{mol}}\right]: \mathrm{B}>\mathrm{T} \ell>\mathrm{A} \ell \approx \mathrm{Ga}>\mathrm{In}$$
Atomic radius (in $$\mathrm{pm}$$) : $$\mathrm{T} \ell>\mathrm{In}>\mathrm{A} \ell>\mathrm{Ga}>\mathrm{B}$$
