Question
P and Q are isomers of dicarboxylic acid C4H4O4 . Both decolorize Br2 /H2O. On heating, P forms the cyclic anhydride. Upon treatment with dilute alkaline KMnO4 , P as well as Q could produce one or more than one from S, T and U.
Compounds formed form P and Q are, respectively
- Optically active S and optically active pair (T, U)
- Optically inactive S and optically inactive pair (T, U)
- Optically active pair (T, U) and optically active S
- Optically inactive pair (T, U) and optically inactive S
The correct answer is: Optically inactive S and optically inactive pair (T, U)

Here we used the concept of slope and slope of a line where we found the slope of the line of side off triangle and found that the slopes of th e lines are same and hence A, B and C were collinear. So it cannot form any triangle and its a straight line on which all the three points are lying.

Amides undergo hydrolysis to yield carboxylic acid plus amine on heating in either aqueous acid or aqueous base. The conditions required for amide hydrolysis are more severe than those required for the hydrolysis of esters, anhydrides or acid chlorides, but the mechanism is similar (nucleophilic acyl substitution). Nucleophilic acyl substitutions involve a tetrahedral intermediate, hence these are quite different from alkyl substitution 
which involves a pentavalent intermediate or transition state. One of the important reactions of esters is their reaction with two equivalent of Grignard reagent to give tertiary alcohols
When 
is treated with two equivalent of methyl magnesium iodide and the product acidified the final product will be

Write the converse of the statement if x + 2 = 6, then x = 4
So we have given a statement and we have to find the what is the converse is. A conditional statement that has the antecedent and consequent switched around is known as a converse statement. So the answer is x + 2 = 6 i.e. if x = 4 then 4 + 2 = 6.
