Verified Answer
Beryllium and aluminium exhibit many properties which are similar. But...
Since, Be and Al have diagonal relationship and so possess similar properties but Be can not form polymeric hydrides.
Alternate Solution:
Beryllium (z = 4)show maximum covalency of 4 but aluminium (z = 13) show maximum covalency of 6. Therefore, aluminium form polymeric hydrides but the beryllium do not form.

Beryllium and aluminium exhibit many properties which are similar. But...
Introduction
Beryllium (Be) and aluminium (Al) are both members of the group 2 and group 13 elements, respectively, and exhibit several similar properties. However, they differ significantly in their ability to exhibit covalency in compounds.
Maximum Covalency
- Covalency Definition: Covalency refers to the number of shared electron pairs between atoms in a molecule.
- Beryllium: Being a small atom, beryllium has a high ionization enthalpy and forms predominantly covalent compounds. However, it typically exhibits a maximum covalency of 4, as seen in its compounds like BeCl₂.
- Aluminium: In contrast, aluminium is larger and can exhibit higher covalency. It can form compounds with a maximum covalency of 6, such as in the case of AlCl₃ (where it can expand its octet).
Comparison of Covalency
- Beryllium's Limitations: The small size and high electronegativity of beryllium restrict its ability to form compounds with higher covalency.
- Aluminium's Versatility: Aluminium, due to its larger atomic size and ability to involve d-orbitals in bonding, can accommodate more electrons, thus it can achieve a higher covalency.
Conclusion
In conclusion, while both elements share similarities, the capacity to exhibit maximum covalency in their compounds distinctly sets them apart. Beryllium is limited to a maximum of 4, while aluminium can reach up to 6, making option 'C' the correct choice.
