ok so but tells you that there's 4 carbons

the 1 bit tell you where the double bond is

that's it
Spoiler:

so you draw a carbon with a double bond attached to another carbon then you draw the other 2 carbons in a row then fill in the spaces with hydrogen remember each carbon can make 4 bonds max

so its CH2=CHCH2CH3

so its CH2=CHCH2CH3
yes

No, that's the structural formula. The displayed formula is in the link Pigster gave.

yes you got it ^-^

the marking scheme says D

4 atoms in total 2 hydrogen and 2 oxygen
multiply 4 by the constant and you get d

would that be the gif?

if so it didn't work on my computer in school :/

That would be the structural formula, the displayed formula is basically the molecule drawn out like this

yea i know i typed the structural formula cuz it hard to type the displayed formula
