How many different types of hydrogens are present in 3 Methylpentane?
four sets
(a) 3-methylpentane has four sets of equivalent hydrogen atoms (Ha through Hd). Two sets of equivalent hydrogen atoms are related by a mirror plane of symmetry (the methyl hydrogen atoms Ha = Ha’ for a total of 6H’s and the methylene hydrogen atoms Hb = Hb’ for a total of four hydrogen atoms).
