draw the structure and u'll know that all hydrogen electrons are bonding bcz hydrogen has only one electron each and if its invlved it need to be bonded by that electron. and each carbon is bonded with four single bonds (1 with the other carbon and 3 with hydrogen atoms) got it >??
Okay thanx well sorry for being rude firstly n see my problem is that in a carbon atom there are 6 electrons n when 4 are bonded 2 of each carbon atom are left unused n arenot bonded so how can no of electrons not bonded be zero? plz explain again.

Carbon's valency is satisfied ( it's four electrons are used in bonding)
Hydrogen's valency is satisfied (it's one electron is used in bonding )

No electrons are left behind!

yeah that's right bt isnt no f electron in carbon 6?

i guess coz both the products formed are soluble
e.g
KNO3(aq)+HCl(aq)--->KCl(aq)+HNO3(aq)
KNo3(aq)+AgCl(s)--->KCl(aq)+AgNO3(aq)
its not suitable as we cant seperate them....
(correct me if m wrong)
have you ever heard about an acid reacting with salt???? KNO3 is salt!!!!
