Which reagent (X) is used to convert I to II

The increasing order of basicity of the following compounds is :
a) 
b) 
c) 
d) 

The major product obtained in the following reaction is

The structural formula of hypo phosphorous acid is

If  represents a pair of lines then λ=

Therefore, the value of  is 2.

The points  and (82, 30) are vertices of

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.

Rate of the reaction is fastest when Z is :

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.

The converse of “if in a triangle ABC, AB =AC then  is

Converse of “if in a triangle ABC, AB =AC then    is In a triangle ABC, if   then AB = AC.

Ester gives nucleophilic addition reaction followed by elimination reaction with carbon nucleophile. When carbon nucleophile is of an ester then the reaction is known as Claisen condensation reaction. This reaction is also carried out between ester and a ketone. A successful Claisen condensation requires an ester with two a-hydrogens and an equivalent amount of base rather than a catalytic amount of base.
In the given reaction
