R-CH-R’

Question 5

OXO PROCESS
CH2=CH2 +Y,Y’,Y’’

Answer 5

CH2=CH2 + CO,H2 [Ca(CO)4]2 will give an aldehyde first and then on reduction alcohol

R-COOH +Y = M
M on reduction gives alcohol
FIND Y AND M

Answer 6

Y = LiAlH4
M= R-CHO

Question 7

R-COOH + R’- OH + Y== X
X + Y’ === ALCOHOL
COMPLETE THE REACTION
WHAT SORT OF METHOD IS THIS ?

Answer 7

Y = H2SO4
Y’ = 2H2/NI

Question 8

CH2=CH2 + PROCESS NAME === ALCOHOL
GIVE THE COMPLETE REACTION AND WHAT KIND OF REACTION IS THIS?

Answer 8

CH2=CH2 + H2O/H+ == CH3-CH-OH

Question 9

CH2=CH2 + Y + Y’ == ALCOHOL
WHAT IS THIS PROCESS CALLED?

Answer 9

Y = 1/2 B2H6
Y’ = H2O/H2O2

Question 10

CHEMICAL PROPERTIES OF ALCOHOL :
1. WITH ACIDS :
R- OH + HCL/SOCL2/HBR ===
2. WITH CONC H2SO4
2R-OH + H2SO4(TEMP) =====
WITH 443K THE SAME REACTION
3. ESTERIFICATION:
R-COOH + R’-OH + Y ====
4. OXIDATION :
R-OH + Y ===
R-R’-R’’ + Y ==
I
OH
5. WITH COPPER
R-OH +Y (TEMP) ==
6. Acetylation

R-OH + Y==

7. With HI IN Presence of Red P
   R-OH + Y + RED P ===
8. WITH GRIGNARD’S REAGENT :
   R-OH + R’MgBr ===
9. DEHYDARTION :
   R-OH + Y + TEMP ===
   AND WHAT ABOUT AT LESS TEMP

10.ACTION WITH CHLORINE :
R-OH + CL2 ==== X + CL2 ==== Y

11. DEHYDRATION OF 2-BUTANOL
12. WITH AMMONIA : 1 DEGREE ONLY
    R-OH + NH3 +Y + TEMP ====

1

Answer 10

1. R-X
2. ETHERS ZT LOW TEMP ALKENES
3. ESTERES Y = H2SO4
4. Y =KmNO4
   5.ALDEHYDE/KETONE DEPENDING ON THE DEGREE OF ALCOHOL Y = CU/573 K
5. Y= CHeck in notebook
6. Y = HI === ALKANE
   8.R’ +Mg - OR
   I
   Br
7. Y= Al2O3 TEmp = 623 K
   == alekenes
   at lower temperature ethers are formed : R-O-R
   10.1. CH3CHO 2,CL3CHO
   11.CH3CH2CHCH3 + H2SO,443 K
   I
   OH
   CH3-CH=CH-CH3 MAJOR , CH3-CH3-CH=CH2 MINOR
   12.CH3CH2OH + H-NH2 + AL2O3 + 635K === CH3CH2NH2(AMINES) + H2O

Question 11

1. C6H5 CL + Y+ X+ Z === PHENOL
2. BENZENE + Y === Z + XOH === M + H+ ====
3. DIAZONIU, SALT + X (TEMp) ===
4. C6H5R + X ==== Y +H+ ====== PHENOL

Answer 11

1. Y = NAOH (AQ) X = 623K, 320 ATM,
2. Y = OLEUM , Z = C6H5SO3H + NAOH === C6H5O-NA+ + H+ === PHENP;
3. • H20 WARM === [HENOL + N2+ HCL
4. X= O2 , Y
