Chapter 7-Alkenes: Structure And Reactivity

Question 1

Alkane formula

Answer 1

C(n)H(2n+2)

Question 2

Using the formula
C14 H23 CL4 N

Answer 2

H23 - 1(from N) + 4(from Cl) = H26
C14 H2 x 14 + 2 = 30
H30-H26 = 4
4/2=2 UN

Question 3

Unsaturated

Answer 3

Fewer hydrogens

Question 4

Saturated

Answer 4

More hydrogens

Question 5

Halogens involved with finding the unsaturated number

Answer 5

Add

Question 6

Oxygens involved with finding the unsaturated number

Answer 6

Ignore

Question 7

Nitrogens involved with finding the unsaturated number

Answer 7

Subtract

Question 8

Naming alkenes

Answer 8

1. Identify longest chain with double bond
2. Number the carbons starting with side closest to double bond
3. Write full name

Question 9

H3C=CH-CH=CH3

Answer 9

1,3-butadiene
Or
Buta-1,3-diene

Question 10

Z configuration

Answer 10

Zame Zide

Question 11

E configuration

Answer 11

Opposite sides

Question 12

Peaks

Answer 12

Transition states

Question 13

Primary

Answer 13

Carbon on the end

Question 14

Secondary

Answer 14

Carbon attached to two carbons/R groups

Question 15

Tertiary

Answer 15

Carbon attached to three carbons/R groups

Question 16

T or f?
A Less highly substituted carbonation is more stable

Answer 16

F. Highly is more stable

Question 17

Stability order. Most to least

Answer 17

Tertiary, secondary, primary, methyl

Question 18

Cis-trans identification

Answer 18

Look at carbons on each end of the double bond and see if they are attached to two different groups. If they are attached to two of the same groups, they cannot be identified as Cis-trans.

Question 19

E-Z configuration

Answer 19

1. Look at carbons on each side of double bond
2. Assign high/low priority to groups on each carbon
3. Two lows on zame zide is Z, two lows on opposite sides in E
