WITH COMPLETE SOLUTIONS
what is a major difference between organic and inorganic
compounds? correct answer: organic contain carbon
what is the reason why there are so many organic compounds?
correct answer: carbon atoms can form stable covalent bonds
with other carbon atoms

chemistry of carbon. this chemistry involves correct answer:
formation of long chains& isomerism
Which applies to the manner in which carbon bonds in alkanes?
correct answer: the bonds are formed with carbon using an sp3
configuration
functional groups are correct answer: to organic chem as
polyatomic ions are to inorganic chem, are chemically bound to
each other in order to develop larger molecules

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 correct answer: NOT: compounds that have a
flat molecular structure,
saturated hydrocarbons, or compounds that cannot have
hydrogens removed and replaced by chlorine

molecular formula C4H10 correct answer: 2
which is a structural isomer of 2-methylbutane correct answer:
pentane
how many structural isomers of C7H16 have 5 carbon atoms in
the longest carbon chain correct answer: 5
A compound is incorrectly named 2-ethyl 1-2,4 -
dimethylhexane. What would be the correct IUPAC name
correct answer: 3,3,5-trimethylheptane
A general formula for cycloalkanes is correct answer: CnH2n

dibromocyclopentane (C5H8Br2) correct answer: 5
how many isomers exist for dichlorocyclopropane (C3H4Cl2)
correct answer: 3
