Question

Hydrogen is a good reducing agent so how it is able to form
compounds with alkali metals which themselves are good reducing
agent and require donation of electron ?? How it forms a covalent
sharing bond with them ?

Dear student,

Hydrogen forms an ionic bond with alkali metals It does not form a
covalent bond An alkali metal loses one electron to achieve a
stable noble gas configuration and hydrogen gains one electron to
achieve a stable noble gas configuration

Example- NaH --------> Na+ + H-
KH -------> K+ + H-
