2
Q

What are organic halides?

3
Q

What is a functional group?

4
Q

5
Q

What are addition reactions?

A

A type of organic reaction of unsaturated hydrocarbons in which a small molecule is added to the double or triple bond. Usually happens in the presence of a catalyst.

6
Q

What is a substitution reaction?

A

An organic reaction that involve breaking a carbon-hydrogen bond in an alkane or aromatic ring and replacing the hydrogen atom with another atom or group of atoms. These rxns occur slowly at room temperature because they lack E (remember that saturated compounds and aromatics are more stable, and don’t tend to react easily with small diatomics unlike alkenes/ynes). Electromagnetic radiation (light) is often necessary for substitution rxns to occur at a noticeable rate.

7

73
Q

How do carboxylic acids compare with alcohols?

A

Carboxylic acids>esters>alcohols>alkenes>alkynes>halides>

78
Q

What is the relationship between structural isomers and boiling points?

A

Straight-chain isomers have higher boiling points than their branched isomers. Branching reduces the surface area between the molecules, and renders mutual attraction less effective (LDF).

79
Q

Why is benzoic acid insoluble in water?

A

Even though it contains the carboxyl group, benzoic acid is insoluble in water because it contains the non-polar benzene ring, which water can’t break down.

Q

How is solubility affected by branching?

A

It increases because less surface area is covered by the non-polar parts of the molecule.

83
Q

How do you find the name of the monomer unit from a diagram?

Draw a line between 2 or 3 carbons and try to find unit that repeats completely until the end. Remember they are usually ethene derivatives, and were initially unsaturated (had double bond- watch naming).
