SEMMELWEIS ENTRANCE EXAM EXAM PREP
QUESTIONS AND ANSWERS STUDY GUIDE
2026
◉ definition of oxidation. Answer: loss of electrons
◉ definition of reduction. Answer: gain of electrons
◉ Displacement Redox reaction. Answer: CuSO4+Zn→Cu+ZnSO4
◉ inorganic carbon compounds. Answer: carbon dioxide, carbon
disulfide, carbonate containing compounds and bicarbonates
◉ nitrogen compounds. Answer: ammonia, hydrogen cyanide,
cyanogen, and nitrous or nitric acid
◉ phosphorus compounds. Answer: derivatives of phosphate
(PO43−), a tetrahedral anion. Phosphorus pentoxide (P4O10) is the
acid anhydride of phosphoric acid, but several intermediates
between the two are known. This waxy white solid reacts vigorously
with water
, ◉ sulfur compounds. Answer: pyrite (iron sulfide), cinnabar
(mercury sulfide), galena (lead sulfide), sphalerite (zinc sulfide), and
stibnite (antimony sulfide)
◉ Types of organic chemical reactions. Answer: Organic reactions
are chemical reactions involving organic compounds. The basic
organic chemistry reaction types are addition reactions, elimination
reactions and substitution reactions
◉ Functional groups. Answer: A specific configuration of atoms
commonly attached to the carbon skeletons of organic molecules
and involved in chemical reactions.
◉ What is an isomer?. Answer: Compound with same atoms, but
arranged differently
◉ Examples of isomers. Answer: glucose and fructose
◉ structural isomers. Answer: Differ in arrangement of atoms.
◉ isomer example. Answer:
◉ Functional group alkanes. Answer: C-C single bond
