So now here I can tell just by looking that we don't have any ihd, right? Because we don't have any PI bonds or rings, so let's just go ahead and do this, right? We know we've got 1, 2, 3, 4, 5, 6, 7 carbons, right? So that's going to be 2n plus 2, which is going to be 2 times 7 plus 2 is going to be C7H16, right? And then we've got that oxygen that we know doesn't count in our in our HD equation, okay? So let's go ahead and give our structural formula, we've got CH3CO8, sorry, that's a hydrogen there CHOH and then we've got 1, 2, 3, 4 CH2's, CH3 at the end. Alright guys, so let's go ahead and move on.
