Question
From the adjacent figure, the correct observation is
- The pressure on the bottom of tank(a) is greater than at the bottom of (b).
- The pressure on the bottom of the tank(a) is smaller than at the bottom of(b)
- The pressure depend on the shape of the container
- The pressure on the bottom of(a) and(b) is the same
The correct answer is: The pressure on the bottom of(a) and(b) is the same
Pressure = hrg i.e. pressure at the bottom is independent of the area of the bottom of the tank. It depends on the height of water upto which the tank is filled with water. As in both the tanks, the levels of water are the same, pressure at the bottom is also the same.

Free radical halogenation takes place in tile presence of light or at high temperature (above 500
C). Formation of halogen free radical intermediate takes place in first step called chain initiation •.
This reaction is mainly given by those compounds which have at least one hydrogen atom present at sp3 -hybrid carbon. Reactivity of 
-hybrid carbon depends on' the reactivity of reaction intermediate.
The relative rate of formation of alkyl radicals by a chlorine radical is:
Relative amount =
Relative amount = Number of hydrogen atoms on the respective carbon x relative reactivity. NBS (N-Bromo succinimide) is used for bromination at allylic and benzylic carbon, whereas 
gives bromination at benzylic, allylic and alkyl carbons Which one of the following compounds will react with NBS?

Nucleophilic substitution reaction" is given by those compounds which have nucleophilic. groups as leaving groups. The weaker the basicity of a group of the substrate, the better is its leaving ability. In nucleophilic substitution reactions, the basicity of leaving group should be less than the incoming nucleophilic group. Nucleophilic substitution reaction at sp3-hybridised carbon is either bimolecular 
or 1lIlim0lecular: 
Bimolecular reaction takes place in single step, involving transition state intermediate. In 
reaction, inversion in configuration takes place. In case of optically active alkyl halides, the inversion in configuration is called Walden "inversion. reaction is preferred if the compound has less steric hindrance. " Unimolecular ( ) reaction" involves two steps and" carbonium ion intermediate. Optically active" substrates give racemic mixture in these" reactions.
