C3H8

Question 6

Butane is?

Answer 6

C4H16

Question 7

How is butane and any “ane” greater than 4 different than the first three “anes”?

Answer 7

Because they can have isomers

Question 8

What are functional groups?

Answer 8

An addition of molecules to create groups with similar characteristic.

Question 9

What are Hydroxyls?

Answer 9

Alcohols (-OH)

Question 10

What are Amines?

Answer 10

(-NH2)

Question 11

What are Carboxyl?

Answer 11

Acids (-COOH)

Question 12

What are the two types of Carbonyl?

Answer 12

1. Aldehyde (-COOH) “al” at the end like mathanAL

2. Ketone (-COO) “one” at end

Question 13

What reaction happens in order to get linkages?

Answer 13

Condensation reactions of de-H2O synthesis, which is removing H2O to build a molecule

Question 14

What kind of linkages can there be?

Answer 14

Ether, Ester, Amide and Peptide

Question 15

Ether is?

Answer 15

Linkage between two hydroxyls (-OH) + (HO-) = H20+O

Question 16

Ester is?

Answer 16

Linkage between hydroxyl and carboxyl (-COOH)+(OH)= H2O + R

Question 17

Amide is?

Answer 17

Linkage between carboxyl and amine (-NH2)+(COOH)= H2O+R

Question 18

Peptide is?

Answer 18

Linkage between amino acids (molecule with COOH and NH2)
