Which process does not occur during formation of CHCl3 from C2H5OH and bleaching powder?
1. Hydrolysis
2. Oxidation
3. Elimination
4. Chlorination
Which of the following options is correct?
1. CH3-CH=CH-CH3 predominates
2. CH2=CH-CH2-CH3 predominates

Mark the appropriate reagent used to distinguish vicinal and geminal dihalides.:
1. | KOH (aq.) | 2. | KOH(alc.) |
3. | Zn dust | 4. | None of these |
A compound A of formula C3H6Cl2 on reaction with alkali can give B of formula C3H6O or C of formula C3H4. B on oxidation gave a compound of the formula C3H6O2. C with dilute H2SO4 containing Hg2+ ion gave D of formula C3H6O, which with bromine and NaOH gave the sodium salt of C2H4O2. Then A is:
1. CH3CH2CHCl2
2. CH3CCl2CH3
3. CH3CHClCH2Cl
4. CH2ClCH2CH2Cl
The compound A forms B with sodium metal and again A forms C with PCl5, but B and C form diethyl ether. Thus A, B and C are:
(1) C2H5OH, C2H5ONa , C2H5Cl
(2) C2H5OH, C2H5Cl, C2H5ONa
(3) C2H5OH, C2H5Cl, C2H4Cl2
(4) C2H5OH, C2H5Cl, C2H5OC2H5
Chlorobenzene is prepared commercially by:
1. Grignard reaction
2. Raschig process
3. Wurtz-Fittig reaction
4. Friedel-Crafts reaction
AgNO3(aq) gives yellow ppt. with:
(1) KIO3 (aq)
(2) KI (aq)

(4) CH2I2
In the given reaction
the product P is:
1. | ![]() |
2. | ![]() |
3. | ![]() |
4. | ![]() |
Consider the reaction
CH3CH2CH2Br + NaCN CH3CH2CH2CN + NaBr
This reaction will be the fastest in
1. ethanol
2. methanol
3. N,N'-dimethylformamide (DMF)
4. water
The reaction of C6H5CH=CHCH3 with HBr produces
