The correct Answer is:
To solve the question regarding the assertion and reason about paracentric and pericentric inversions, we can follow these steps: ### Step 1: Understand the Definitions - **Paracentric Inversion**: This type of inversion occurs when the inverted segment does not include the centromere. Thus, the centromere remains outside the inverted segment. - **Pericentric Inversion**: In this type of inversion, the inverted segment includes the centromere, meaning the centromere is part of the inverted segment. ### Step 2: Analyze the Assertion - The assertion states: "In paracentric inversions the centromere is outside the inverted segment." - This statement is **true** because, by definition, paracentric inversions do not involve the centromere. ### Step 3: Analyze the Reason - The reason states: "In pericentric inversion, the inverted segment includes the centromere." - This statement is also **true** as pericentric inversions are defined by the inclusion of the centromere in the inverted segment. ### Step 4: Determine the Relationship Between Assertion and Reason - While both the assertion and reason are true, the reason does not explain the assertion. The assertion is focused on paracentric inversion, while the reason discusses pericentric inversion, which is a different concept. ### Step 5: Choose the Correct Option - Based on the analysis, the correct option is: **Both assertion and reason are true, but the reason is not the correct explanation of the assertion.** ### Final Answer The correct answer is Option 2: Both assertion and reason are true, but reason is not the correct explanation of assertion. ---

Nucleophilic aliphatic substitution reaction is mainly of two types: S_(N)1 and S_(N)2 . The S_(N)1 mechanism is a two step process. Reaction velocity of S_(N)1 reaction depends only on the concentration of the substrate. Since product formation takes place by the formation of carbocation, optically active substrate gives (+) and (-) forms of the product. In most of the cases the product usually consits of 5-20% inverted product and 80-95% racemised species. The more stable the carbocation, the greater is the proportion of racemisation. In solvolysis reaction, the more nucleophilic the solvent, the greater is the proportion of inversion. For the gives reaction, Which substrate will give maximum racemisation?

SN reaction is given by these compounds, which have a nuclophilic group and a good leaving EWG . It should be stable after leaving with bonding pair of overline(e)'s and it should have high polarisability. Nucliphilic aliphatic substituion reaction is mainly of two types SN^(-1) and SN^(2). SN^(-1) mechanism is a two step process. Reaction velocity of SN^(-1) depends only on the concentration of the subtrate. It proceeds via the formation of carbocation, optically active substrate gives (o+) and (o-) froms of the product. In most of the cases, the product usually consists of 5-20% inverted and (95-80%) racemised species. The more stable is the carbocation, the greater is the propotion of racemission. In solvolysis reaction, the more nucleophillic is the solvent, the greater is the proportion of inversion. Which of the following gives SN^(1) reaction? Select the correct answer.

Transformations of inverse trigonometric functions need to be handled with care. Consider the identity sin2theta=(2tantheta)/(1+tan^2theta) in its domain of definition. Suppose we set tantheta=x , we have sin2theta=(2x)/(1+x^2) Taking sin^(-1) of both sides yields 2theta=sin^(-1).(2x)/1+x^2i.e.,2tan^(-1)x=sin^(-1).(2x)/(1+ x^2) . But we will discover that the above identity is not valid for all x. Choose x=sqrt3, LHS =2tan^(-1)sqrt3=2xxpi/3=(2pi)/3, RHS=sin.(2sqrt3)/(1+3)=sin^(-1).(sqrt3)/2=pi/3 . And so left hand and right hand side don't match. The reason is that we have disregarded the principal values of inverse functions. So it is well to remember that the iverse trigonometric formmulae have restrictions attached to the argument. When the values of x lie outside the interval of validity then the formula needs to be corrected. Let f(x)=sin^(-1)(x)/(1+x^2),g(x)=2tan^(-1)x . Then the largest interval in R on which f and g both are agree
