(a)
Interpretation:
The given reaction needs to be classified as substitution, elimination, addition or condensation.
Concept introduction:
In a substitution reaction, one

Answer to Problem 18SSC
Addition reaction.
Explanation of Solution
The given reaction is as follows:
Here, addition of hydrogen molecule takes place to
Thus, the above reaction is an addition reaction.
(b)
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
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.
