Answer 9

oxime (C=NOH)

Question 10

Answer 10

hydrazone (C=NNH2)

Question 11

reagent for converting all OH groups on cyclic hemiacetal to ester and reaction type

Answer 11

CH3I/ Ag2O through Nu- substitution of akyl halide

Question 12

reagent for converting all OH groups on cyclic hemiacetal to ether and reaction type

Answer 12

H3C-(C=O)-O-(C=O) -CH3 - ethanoic anhydride or (CH3CO)2O which adds C=OCH3

Question 13

What is the reagent for converting cyclic hemiacetal to glycoside

Answer 13

alcohol in presence of acid : ROH/H+

Question 14

Glycosides can be converted to free monosaccharides by adding what

Answer 14

aqueous acid: H3O+/ H+

Question 15

What is a strong source of Cl- able to turn alcohol into akyl halide and carboxylic acid into acyl chloride

Answer 15

SOCl2

Question 16

What is the dehydrating agent that works on carboxylic acids and what type of anhydrides does it make

Answer 16

P2O5, symmetrical anhydrides- two of the same carboxylic acids join together

Question 17

How do you figure out the reagent needed for nucleophilic acyl substitution for acid chlorides and anhydrides

Answer 17

Look at what has been substituted in place of [Cl] or [OCOR’] and just add an H to it to make it the reagent

Question 18

What reagent is needed to make esters from simple carboxyllic acid and alcohol

Answer 18

H+ (lots)

Question 19

What are the reagents for amide hydrolysis and getting the amine from it

Answer 19

70% aq H2SO4 and heat or strong aqueous base. To get amine from it you have to add some OH- to get rid of the extra H+ on the ammonia group added to R.

Question 20

If you need to deprotanate an amino acid that has been formed as a NH3+ what do you use

Answer 20

OH-

Question 21

How do you get an aryl amine. What do you start with and what do you use

Answer 21

Start with NO2 on the ring. Use 1. Fe/H3O+ and 2.OH-

Question 22

What facilitates homolytic bond cleavage to get radicals

Answer 22

Hv (light) or heat

Question 23

What are the reagents for nu- sub of an alcohol to an akyl halide

Answer 23

1 and 2’ alcohols = SOCl2

3’ alcohols = HX (Cl or Br)
