Total questions: 10
Worksheet time: 5mins
In order to be classified as chiral, a molecule must have:
3 different groups surrounding the carbon atom
4 different groups surrounding the carbon atom
0 different groups surrounding the carbon atom
less than 4 different groups surrounding the carbon atom
Different compounds with the same molecular formula are known as:
constitutional isomers
stereoisomers
Isomers
isomeres
Molecules that differ in the way the atoms are connected to each other are known as:
cis and trans molecules
Constitutional isomers
stereoisomers
chiral molecules
These are an example of:
stereoisomers
non isomers
ethanol
different molecules
To superimpose a molecule and its mirror image you can perform any rotation but you
make more bonds
can break bonds
cannot break bonds
make a new molecule
A molecule is classified as tetrahedral, does this make it chiral?
Always
Never
Only if it has a C=C
Only if it has 4 different groups attached
CH2CH3, CH3, H, and Br are attached to a carbon making it
an achiral center
an isomer
a stereoisomer
a chiral center
CH2 and CH3 groups have more than one H atom bonded to the same C, so those C’s are _____ chirality centers.
always
never
sometimes
rarely
A C that is part of a _____ does not have four groups around it, so it is never a chirality center.
single bond
ring
line structure
multiple bond
Is C3 a chiral center
yes
yes and no
no
none of the above
