Why HCl conducts electricity while Glucose doesn't conduct elecricity, though both contains the hydrogen ions.at least of 200-350 words

There are 2 types of basic compounds- ionic and covalent. 
Ionic bonds are formed when a metal gives up valence (outer level electron shell)
electrons to a nonmetal.  Covalent bonds form between 2 nonmetals (the same kind or
different) and they SHARE valence electrons instead of exchanging
them.


Hydrogen atoms only have 1 electron which means their
outer most shell is their valence shell.  This means that this electron is available for
transfer in the case of an ionic bond and sharing in the case of a covalent bond. 
Hydrogen is one of a few pesky elements that can behave differently than the standard
rules of the periodic table describe.  It is due to its simple and small
structure.


So, if hydrogen is in the vicinity of certain
nonmetals its electron will be pulled away from it to make the valence shell of the
nonmetal "happy" or filled to capacity.  If, on the other hand it is in the vicinity
of other nonmetals, it will share its electron and that nonmetal will share its outer
electron with hydrogen making its 1 electron shell filled or
"happy."


Electricity is the flow of electrons by definition
so a source of electrons would be needed to get electricity to flow through an object. 
When HCl is dissolved in water the ionic bond is broken and free electrons (electrolytes
or charged particles) or given off so electricity is allowed to
flow. 


If, on the other hand sugar (glucose) is placed in
water, the covalent bonds are not broken so no source of electrons (electrolytes) are
available for electrical flow.
