CnH2n+1
|
What is the geometry of carbon atoms in alkanes?
linear
trigonal planar
octahedral
tetrahedral
|
Approximately, what is the bond angle in a tetrahedral geometry?
120°
90°
109.5°
180°
|
How do longer carbon chains affect the boiling point of alkanes?
they increase the boiling point
they decrease the boiling point
they cause the alkane to become unsaturated
they have no effect on the boiling point
|
Which type of intermolecular force is responsible for the boiling point trends in alkanes?
induced dipole-dipole forces
hydrogen bonding
dipole-dipole forces
ion-dipole forces
|
Which alkane is expected to have a higher boiling point?
ethane (C2H6)
propane (C3H8)
methane (CH4)
butane (C4H10)
|
What is the reason for the difference in boiling points between butane and methylpropane?
butane has a longer carbon chain
butane is a straight-chain alkane, allowing closer packing
methylpropane has a longer carbon chain
methylpropane is a straight-chain alkane, allowing closer packing
|
Which of the following is an example of an alkane?
C4H6
C5H8
C3H8
C2H4
|
What is the general formula for cycloalkanes?
CnH2n-2
CnH2n+1
CnH2n
CnH2n+2
|
Alkanes are hydrocarbons, meaning they contain no double or triple bonds.
