Alkenes, Alkynes and Aromatics

Question 1

Naming Alkenes, -kynes and Aromatics

Answer 1

Same way as Alkanes. Except, the chain must contain the double or triple bond and it must receive the lowest numbered carbon possible

Question 2

Isomers Cis and Trans

Answer 2

Cis Isomers- the groups attach on same side of bond Trans Isomers- the groups attach on the opposing sides

Question 3

Alkene and Alkyne Properties

Answer 3

Same as alkynes minus that they are more reactive bc they have a double/triple bond.

Question 4

Common Reactions for Alkenes and Alkynes

Answer 4

Addition Elimination Substitution Rearrangement Also: Hydrogenation Hydration Halogenation Hydrohalogenation

Question 5

Polymer and Monomer

Answer 5

Polymer- a large molecule formed by repetitive bonding of smaller molecules, monomers

Question 6

Resonance

Answer 6

The idea that there are no set double bonds between specific carbons. It’s like a mutual double bond shared by all

Question 7

Naming Aromatics

Answer 7

Same as Alkenes and Alkynes.

Except, when other substituent is 2 C’s away it has prefix of ortho-, 3 c’s away meta-, 4 C’s away para-

Also, if benzene IS the substituent is is called phenyl ex. 3-phenylheptane

Question 8

Aromatic Reaction

Answer 8

Electrophilic Substitution: Nitration Sulfonation Halogenation
