In chemistry, a hydride is formally the anion of hydrogen, H⁻. The term is applied loosely. At one extreme, all compounds containing covalently bound H atoms are called hydrides: water is a hydride of oxygen, ammonia is a hydride of nitrogen, etc.

Positively loaded or neutral species are called electrophiles that are deficient in electrons and can accept a couple of electrons. These are also called species that love electron (philic).
- The term electrophile can be split into “electro” derived from electron and “phile” which means loving.
- They are electron deficient and hence electrons loving.
- They are positively charged or neutrally charged.
- They attract electrons. Movement of electrons depends on the density.
- They move from high-density area to low density area.
- They undergo electrophilic addition and electrophilic substitution reactions.
- An electrophile is also called as Lewis acid.

Internal energy is a state function i.e. depends only upon the state of the system and is independent of the method by which this state has been attained.
Let us change the internal energy of the system by doing work called adiabatic work. This can be done in two ways:
(1) By doing mechanical work by rotating a set of small paddles.
(2) By doing electrical work with the help of an immersion rod.
