EVALUATION 2026 QUESTION BANK FULL
SOLUTION SET
◉ what is the reason why there are so many organic compounds?
Answer: carbon atoms can form stable covalent bonds with other
carbon atoms
◉ the vast number of organic compounds is due to the unique
chemistry of carbon. this chemistry involves
Answer: formation of long chains& isomerism
◉ Which applies to the manner in which carbon bonds in alkanes?
Answer: the bonds are formed with carbon using an sp3
configuration
◉ functional groups are
Answer: to organic chem as polyatomic ions are to inorganic chem,
are chemically bound to each other in order to develop larger
molecules
◉ the alkanes represent one family of organic compounds
,Answer: that is composed of carbon and hydrogen
◉ formulas of organic compounds
Answer: CH3CH2COOH, CH3CH2OH,
CH3CH3CH3
◉ which is an alcohol
Answer: CH3CH2OH
◉ what is meant by the term "saturated" when describing
hydrocarbons
Answer: they are saturated with hydrogen and only have single
bonds between carbons
◉ correct statements on the naming of organic compounds
Answer: many compounds have been known long enough to have
common names, the naming system of organic compounds is set by
IUPAC rules, & the naming system requires that the longest carbon
chain must always be found
◉ cycloalkanes are
Answer: NOT: compounds that have a flat molecular structure,
,saturated hydrocarbons, or compounds that cannot have hydrogens
removed and replaced by chlorine
◉ which of the following term applies to the alkanes
Answer: hydrophobic
◉ what is a characteristic shared by the alkanes
Answer: flammable
◉ which of the following is a use for alkanes?
Answer: a. fuel
b. lubricant
c. solvent
D. MORE THAN ONE IS CORRECT
◉ which of the following represent a saturated hyrdocarbon
Answer: C2H6
◉ All of the members of the alkane series of hydrocarbons have the
general formula __
Answer: CnH2n+2
, ◉ which of the following compounds can exhibit structural
isomerism?
Answer: butane
◉ how many structural isomers are possible for compounds with a
molecular formula C4H10
Answer: 2
◉ which is a structural isomer of 2-methylbutane
Answer: pentane
◉ how many structural isomers of C7H16 have 5 carbon atoms in
the longest carbon chain
Answer: 5
◉ A compound is incorrectly named 2-ethyl 1-2,4 - dimethylhexane.
What would be the correct IUPAC name
Answer: 3,3,5-trimethylheptane
