РН3 - ковалентная полярная
AlH3 - ионная наверно, не уверена

Answer 2

Formation and Type of Chemical Bonds for I2, PH3, AlH3

Iodine (I2): Iodine (I2) is formed through the sharing of electrons between two iodine atoms, resulting in a covalent bond. The type of chemical bond in I2 is a covalent bond, specifically a nonpolar covalent bond due to the similar electronegativities of the two iodine atoms.

Phosphine (PH3): Phosphine (PH3) is formed through the sharing of electrons between phosphorus and hydrogen atoms, resulting in covalent bonds. The type of chemical bond in PH3 is a covalent bond, specifically a polar covalent bond due to the difference in electronegativities between phosphorus and hydrogen.

Aluminum Hydride (AlH3): Aluminum hydride (AlH3) is formed through the sharing of electrons between aluminum and hydrogen atoms, resulting in covalent bonds. The type of chemical bond in AlH3 is a covalent bond, specifically a polar covalent bond due to the difference in electronegativities between aluminum and hydrogen.

In summary, I2 forms nonpolar covalent bonds, PH3 forms polar covalent bonds, and AlH3 also forms polar covalent bonds.
