1.	How many monobromo derivatives are obtained when 2-methylbutane is subjected to photobromination ?
Answer» Solution :The NUMBER of different monohalogen derivatives OBTAINED from any alkane depends upon the number of different types of HYDROGENS it contains. Now 2-methylbutane contains four different SETS of equivalent hydrogens (as shown by encircled integers ) and hencegives four monobromo derivatives on photobromination.
