All right, so looking at your questions here, your first question says, was the compound you synthesized pure? the answer would be yes.
00:07
I looked up the melting point of this p -nitroacetylamide, and it says it's 215 degrees celsius.
00:14
And you said when you did your lab that the melting point was between 213 and 215 degrees celsius.
00:21
So the smaller this range and the closer to the ideal number, the more pure that it is.
00:28
The only way it could be more pure is that it would have melted, started and ended right at 215 degrees celsius.
00:34
But in general, i would say, yes, it was pure.
00:38
And number two, it says compare your yield, which was 10 percent with the typical yield, which is 40 percent.
00:46
Is it lower? yes, it's lower.
00:48
So that's bad.
00:49
So then it says we're supposed to give possible reasons for why it might be lower.
00:55
So here's a few...
