- It is necessary to avoid even traces of moisture from a Grignard reagent.
- Chloroform is stored in closed dark coloured bottles completely filled.
- The carbon– oxygen bond length in phenol is slightly less than that in methanol.
- Preparation of Sec-Butyl alcohol from ethanal
- Preparation of Phenol from Aniline.

- Carboxylic acid is a stronger acid than phenol. Why? 2
- How will you convert ethanal into the following compounds? 2
the products formed when cyclohexanecarbaldehyde reacts with
Semicarbazide and weak acid
- P4 + SOCl2 ---------------à
- 4 AgNO3 + 2H2O + H3PO4 -------------à
- NaCl + MnO2 + H2SO4 ------------------à
- H3PO2 act as monobasic acid.
- Interhalogen compounds are more reactive than halogens
- Bond dissociation energy of F2 is smaller than Cl2.
- Sc, the first member of first transition series doesn’t exhibit variable oxidation state. Account for the following
- Transition metals have a strong tendency to form complexes.
- Zirconium (atomic no 40) and hafnium (atomic no 72) exhibit similar properties.
