Chapter 22, Problem 2STP

Interpretation Introduction

Interpretation:

The type of the given reaction needs to be determined.

Concept introduction:

In a substitution reaction, one functional group is replaced by other functional group. In addition reaction, two reactants simply add to form a single product. In condensation reaction, addition of two reactants takes place after removal of water molecule. The elimination reaction results when removal of two substituent groups takes place from a molecule.

Answer to Problem 2STP

Correct Answer: Option (b)

Explanation of Solution

Reason for correct option:

The given reaction is as follows:

In the above reaction, addition of two reactants takes place which results in the removal of water molecule. Thus, this is a condensation reaction.

Therefore, option (b) is correct.

Conclusion

Reason for incorrect option: In a substitution reaction, one functional group is replaced by other functional group. Since, there is no replacement of functional group takes place thus; it is not a substitution reaction.

In addition reaction, two reactants simply add to form a single product. Since, there is removal water takes place or two products are formed. This is not an addition reaction.

The elimination reaction results when removal of two substituent groups takes place from a molecule. Here, addition of two molecules takes place which results in the removal of H₂O molecule thus; this is not an elimination reaction.

Therefore, options (a), (c) and (d) are incorrect.
