Chapter 22.4, Problem 18SSC

Interpretation Introduction

(a)

Interpretation:

The given reaction needs to be classified as substitution, elimination, addition or condensation.

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 18SSC

Addition reaction.

Explanation of Solution

The given reaction is as follows:

Here, addition of hydrogen molecule takes place to alkene molecule which results in the formation of alkane.

Thus, the above reaction is an addition reaction.

Answer to Problem 18SSC

Elimination reaction.

Explanation of Solution

The given reaction is as follows:

In the above reaction, alcohol form alkene after removal of water molecule. Since, water molecule is released or eliminated from alcohol thus, it is an elimination reaction.
