A few questions regarding the synthesis of p-bromoaniline, Ask an Expert

Academics

A few questions regarding the synthesis of p-bromoaniline labreally bother me and would like someone to clear them up.

1) Why do we have to parafilm or cover the beaker containingp-bromoaniline before we put it away for next lab? Is it so that itdoes not get oxidized by oxygen? If so, how?

2) If there is some alcohol left in the product (p-bromoaniline),is it safe to run IR without removing it? I would assume that therewould be an O-H peak in the IR if alcohol is not removed and itwould give a false result. Please explain. If we remove the alcohol, what is the risk associated with it?
