Midterm 1

Question 1

Alkane (not a functional group)

Answer 1

No C-C multiple bonds
Hydrocarbons

Question 2

Alkene

Answer 2

Has 1 C=C double bond
Sigma + pi bond

Question 3

Alkyne

Answer 3

C-C triple bond
Sigma pi pi bond

Question 4

Aromatic hydrocarbons

Answer 4

3 C-C double bonds
Usually a ring

Question 5

Alkyl halides

Answer 5

Contains F, Cl, Br, I

Question 6

Alcohol (hydroxyl)

Answer 6

Has R-O-H

Question 7

Ethers

Answer 7

Contains C-O bonds
Both are sp3 hybridized
Geometry is bent

Question 8

Amine

Answer 8

Alkyl group bonded to nitrogen

Question 9

Aldehyde/Ketone

Answer 9

Carbonyl group C=O
Aldehyde: carbonyl carbon bonded to alkyl group and 1 hydrogen atom
Ketone: carbonyl carbon bonded to two alkyl groups

Question 10

Carboxylic acids

Answer 10

One alkyl group and hydroxyl group to carbonyl carbon
So O=c-oh and ch3

Question 11

Boiling point

Answer 11

High BP = more surface area (a chain will be higher than t butyl)
Low BP= more branches the less surface area

Question 12

Melting point

Answer 12

More planes of symmetry = higher melting point

Question 13

Sp3

Answer 13

109 degrees
Either bent (2) trigonal pyramidal (3) or tetrahedral (4)

Question 14

Sp2

Answer 14

120 degrees
trigonal planar (3 groups)

Question 15

SP

Answer 15

180 degrees
Linear

Question 16

Amides

Answer 16

Contains carbonyl group C=O
nitrogen to carbonyl group to one or two alkyl groups

Question 17

Esters

Answer 17

RCOOR
