Terms: carbonium ion, hydride ion, pyrolysis furnace, 

Two distinct classes of carbonium ions have come to be recognized. The first are the “classical” carbonium ions, which contain a trivalent carbon atom centre. 
The second class of carbonium ions includes the pentacoordinated, or “nonclassical,” carbonium ions, which have three single bonds, each joining the carbon atom to one other atom, and a two-electron bond that connects three atoms, rather than the usual two, with a single electron pair.

The molecule, atom or ion that loses the electron is called a reducing agent (electron donor). The reducing agent gives the electron to the accepting molecule, atom or ion on its own.

The molecule, atom or ion that accepts the electron is called an oxidising agent (electron acceptor). Oxidising agents accept electrons from others readily. 

 Some sugars can act as reducing agents, which means they give electrons to other molecules, atoms or ions. But, starch cannot act as a reducing agent. ...  .. Link  

Reducing Sugar Definition :

What is reducing sugar? The type of sugar that acts as the reducing agent and can effectively donate electrons to some other molecule by oxidizing it is called reducing sugar. In another definition, any sugar that tends to act as the reducing agent since it has either an aldehyde group (-CHO) or the ketone group (-CO-) is called reducing sugar. ... Link
