    Hydrogen can combine with elements in three ways 1. When it looses its electron (with Metals ) 2. When it gains an electron (with non metals). 3 by electron sharing or covalent bond with C Since metals have tendency to loose their electron they for + ions eg Na+ or K+. When hydrogen combine with these metals it forms hydrides. Eg: NaH sodium hydride or KH potassium hydride. So basically hydride is H - ion . Hydrogen ion with negative charge.

    Hyperconjugation effect: It is an extension of resonance effect, as it involves delocalization of sigma electrons of C-H bond of an alkyl group directly attached to an atom of unsaturated system or an atom with an unshared p orbital.

    The inductive effect of alkyl group is reversed when attached to an unsaturated system such as double bonds or benzene rings. This change in the behaviour is called as hyperconjugation effect.

    The order of I- effect in alkyl gr. of a saturated system is ; (CH3)3 C-> (CH3)2 CH- > CH3CH2- > CH3 -

    This order is reversed in unsaturated system due to hyperconjugation effect. The effect works as;

    Here structure 1, 2 and 3 are called as hyperconjugative structures.

    It is also shown that, the hyperconjugation depends on no. of alfa H atoms, and so as much is the hydrogen atoms that much will be the hyperconjugative structures.
