| 'condensed structural formula' is CH3CH2CH3
'expanded structural formula' is
H H H
| | |
H - C - C - C - H
| | |
H H H
they *should* specify, but if they dont, be safe and do both. its not like it takes that much longer, and if they didnt say, they cant mark you wrong. most of the time if they ask you to give a formula for something they are looking for the bonds anyway.
and make sure you put H's at the end of all the bonds and dont forget the bond between the O and H in an O-H group. i have seen some teachers forget/tell students not to bother - BAD idea
