this isn't car related but i am having a test later on in biology and we are getting tested on molecular structure, and chemical bonds etc. my question is on covalent bonds, i know it is possible to have a "double bond" but when and why? thats pretty much the only thing i am confused about, please help me out!!!

 

dude... you should have studied

I passed bio with an A, chem with a B...

I know the answer...

but, it should DEFINATELY be in your book.

 

i am studying and have been, this is the only thing i don't understand. its in my book but it just gives the definition, i just need a quick explanation, its cool if you don't want to help me out no problem.

 

bonds are created by positive and negative atoms (electrons and protons). There in, each substance has a small positive or negative charge. A bond is created when the molecules share electrons

Hydrogen, dirty hydrogen, is one of the few molecules that will attract and hold bonds with smaller, weaker molecules. It can bridge things sometimes because it likes to share its electrons.

Basically, a double, triple, quadrouple, you name it bond... will occur when when the atoms share electrons...


I think thats what your looking for.

Edit: So if hydrogen and carbon are sharing 4 pairs of electrons with carbon, there is a quadruple bond.

 

i understand that, let me see if i can get a pic of what i don't understand

 

wtf does this have to do with neons?

BAN BAN BAN

 

lmao!!!!


it shoudl TECHNICALLY be moved to OT

 

what i dont understand is why there is a double bond to Oxygen from Carbon...(circled in red)

it will make it faster. lol.

 

OHHH!!! Thats EASY!!!!!


Basically, if your taking CH3CO2Na

that is saying Carbon and hydrogen share 3 bonds, attatched to a carbon with 2 bonds (aka a double bond)- attatched to sodium

you could TECHNICALLY draw three lines from one hydrogen to the carbon... as it is a tripple bond.
