Abstract

Glavni cilj istraživačkog dijela ovog diplomskog rada bio je ispitati kakve su mogućnosti
sinteze bakrovih(II) acetata i kloracetata koji u apikalnim položajima imaju vezane molekule
alkohola ili piridinskih derivata s bezvodnim binuklearnim karboksilatima bez posebnog
izoliranja reakcijskog sustava. Provedene su otopinske i mehanokemijske sinteze. Kao otapala
korišteni su prop-1-ol, but-1-ol, aceton i kloroform, a kao potencijalni apikalni piridinski adendi
molekule piridina, 2-, 3- i 4-pikolina te 2,4-, 2,6- i 3,5-lutidina. Bolju perspektivu imaju sinteze
provedene u prop-1-olu. Mehanokemijske sinteze daju vrlo amorfizirane produkte.
U metodičkom dijelu rada napravljena je usporedna kritička analiza starog i novog
srednjoškolskog nastavnog programa pri čemu su određene njihove sličnosti i razlike te
komparativne prednosti i mane novog nastavnog programa. Dodatno je osmišljen i pripremljen
nastavni materijal potreban za provođenje jednog 90-minutnog nastavnog sata utemeljnog na
nastavnoj strategiji učenja otkrivanjem, koji može poslužiti kao predložak za osvježivanje
nastavnih sadržaja svakodnevne nastavne prakse.

Abstract (english)

Thesis deals with solution and mechanochemical syntheses of copper(II) acetates and
chloracetates that are apically decorated with alcohol molecules or pyridine derivates from
anhydrous binuclear starting materials. Prop-1-ol, but-1-ol, acetone and chloroform were used
as solvents and 2-, 3- and 4-picoline and 2,4-, 2,6- and 3,5-lutidine as potential apical ligands.
Better results were achieved in prop-1-ol. Mechanochemical syntheses produced amorphous
products.
In methodical part of the thesis an comparative study of old and new primary and highschool
syllabuses of chemistry is given. Comparative benefits and potentail faults of new syllabuses
are stressed. Additionally, a 90-minute lesson based on guided inquiry learning strategy with
simple, cheap and available experiments and teaching materials was proposed.
