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)
(3) CHI3
(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
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
Mark the appropriate reagent used to distinguish vicinal and geminal dihalides.:
