rxns organic chem

Question 1

reactions of alkanes

Answer 1

combustion and substitution

Question 2

reaction of alkene/alkyne

Answer 2

add two atom or groups to a multiple bond, turning it to a single bond; hydrogenation, halogenation, hydrohalogenation

Question 3

alcohol reactions

Answer 3

substitution, acid-catalyzed elimination, addition

Question 4

combustion

Answer 4

CxHy + (x+y/4)O2 -> XCO2 + y/2 H2O

Question 5

substitution

Answer 5

CH4 + CL2 (or F2, Br2) -> CH3Cl + HCl

Question 6

hydrogenation

Answer 6

adding H2 to make alkanes

Question 7

halogenation

Answer 7

adding Cl2 or Br2 to

Question 8

hydrohalogenation

Answer 8

add HF/HCl/HBr/Hi; which ever carbon has more H attached is one that receives H, fewer H receives halogen

Question 9

substitution (alcohol)

Answer 9

CH3OH + HCl -> CH3Cl + H2O

Question 10

acid-catalyzed elimination

Answer 10

CH3CH2OH (H2SO4) -> CH2=CH2 + H2O; addition is opposite

Question 11

oxidizing/reducing of groups

Answer 11

alakne -> alkohol -> aldehyde -> carboxylic acid

OX inc. ->
<- RED inc.

Question 12

ketone/aldehyde addition of C=O

Answer 12

polar molecules add across the C=O of aldehydes/ketones, + part attaching to O, O single bonded

Question 13

ester condensation rxns

Answer 13

acid + alcohol -> ester + water

Question 14

what is an ester made of

Answer 14

carboxylic acid and alcohol

Question 15

are ethers reactive?

Answer 15

no unreactive, good solvents

Question 16

amines reaction w/ strong acid

Answer 16

amine + strong acids -> to form ammonium

Question 17

amines reaction w? carboxylic acid

Answer 17

condensation run to form amides
