Dear teachers,
Would you be kind enough to explain to me in plain English the difference between previous, previously, tentative and tentatively in the following sentences?
Previous systematic investigation of unsymmetrical ketons in the Schmidt reaction have been concerned principally with the effect of branching in alkygroups.
Extraction of cornstalks, previously hydrolyzed with dilute hydrochloric acid according to Morgal.
These compounds have been previously assigned the following structure.
Nearly all previous stidies on the ion exchange behaviour of zirconium and halfium have been limited to investigations of the separation of these two elements.
Our experiments have led to the tentative conclusion that these mixed solvent systems facilitate cellulose reactions.
No particular vibrational mode can be suggested at present which might account for this correlation which must therefore be regarded as as tentative one.
In addition, the week band was noted by some workers and assigned tentatively to an additional NH absorption.
Further evidence hearing on the correctness of a tentatively assigned electrode reaction can be secured.
Thank you for your efforts.
Regards,
V.
