See card 1
3,4-diethylcyclopentene
methoxypropane
See card 1
What happens to the boiling and melting point of alkanes, alkenes and alkynes as their carbon chains get longer?
As the chains of alkanes, alkenes and alkynes increase their boiling points increase due to an increase in LDF.
A student named an alkane 2-ethylpropane. The correct IUPAC name of the alkane is?
2-methylbutane
If a benzene group is bonded to a complicated hydrocarbon chain what is it known as?
phenyl
See card 2
trans- but-2-ene
cyclohexylpropanoate
Card 2
What has a higher boiling point alcohols or their corresponding unsubstituted alkanes and why?
Alcohols because of of hydrogen bonding.
See drawing: A student named this compound phenyl methanoate why is the student wrong?
( see drawing)
methyl benzoate
Explain the difference between a primary, secondary and tertiary amine.
Primary amine - The nitrogen is attached to one carbons
Secondary amine- The nitrogen is attached to two carbons
Tertiary amine- The nitrogen is attached to three carbons
See card 3
benzene-1,2-diol
2,2,4-trimethypentane
See card 3
Are primary, secondary or tertiary amines more soluble in water and why?
Primary because they can hydrogen bond twice.
A student named an aldehyde 5-ethylhexanal. What is the correct IUPAC name for this aldehyde?
5-methylheptanal
How many bonds form to hydrogen, carbon, nitrogen and oxygen?
HONC
See card 4
N-ethyl-N-methylbenzamide
N,N-diisopropyl-2-methylbutanamide
See card 4
Why are both aldehydes or alcohols soluble in water? Which is more soluble?
Alcohols can hydrogen bond where as aldehydes only have dipole-dipole attraction. Alcohols more soluble.
A student named an alkane 1,1-diisopropyl-2-methylpropane. What is the correct IUPAC name for this alkane?
3-isopropyl-2,4-dimethylpentane
What is the difference between a diastereomer and an enantiomer?
Diasteromer: based on the presence of a double bond
Enantiomer: Mirror images of each other
See card 5
1-methyl-2-phenyl-butylpropanoate
7-butan-2-yl-3-chloro-8-ethyldec-2-ene
See card 5
What type of esters are soluble in water?
Small esters
A student named a structure 1-methyl-3-phenylpropanal what is wrong with this?
Carbon can only form 4 bonds.
To be an aldehyde have to remove the methyl group and be named: 3-phenylpropanal.
Are these two compounds isomers of each other? If so what kind?
( See drawing)
Yes, Constitutional or structural isomers: Atoms bonded in different sequences.
