CHEM 1020 MIDTERM TEST PAPER 2026
QUESTIONS WITH COMPLETE SOLUTIONS
COMPREHENSIVE STUDY GUIDE GRADED
A+
⩥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
