What does -en mean?
cont a C=C double bond
Methyl Group
CH3
Ethyl Group

What is structural isomerism?
Mol which have the same molecular formula but a different structural formula
What is chain isomerism?
Same molecular form but a diff arrangement of the atoms in the C chain
What is positional isomerism?
Mol have the same funct group but it is in a dif pos in the mol
What is funct group isomerism?
Mol have the same mol formula but have dif funct groups
What is geometric isomerism?
Mol which have the same str formula but dif arrangement of atoms due to the pres of 1/more C=C bonds
Z isomerism
Same side
E isomerism
opposite sides
Which E or Z is given a higher priority?
Higher atomic number given high priority
What are the req for geometric isomerism?
Restricted rotation due to C=C double bond
Two different groups of the LHS and two different groups on the RHS
In trans bonding in terms of pos and priority in double bond where is E?
Highest priority groups are on opposite sides of the double bond
In cis bonding in terms of pos and priority in double bond where is Z?
Highest priority groups are on the same side of the double bond

NO
Does pent-2-ene have gi?
YES
