How many primary, secondary and tertiary hydrogen atoms repsectively are present in isobutane?
  1. 0,1 and 3
  2. 3,1 and 0
  3. 9,0 and 1
  4. 1,0 and 3

Solution

Carbons have a special terminology to describe how many other carbons they are attached to. Hydrogen atoms are also classified in this manner. A hydrogen atom attached to a primary, secondary and tertiary carbon atom is called a primary, secondary and tertiary hydrogen respectively. Hence, isobutane, has nine primary hydrogens and one tertiary hydrogen. Structure of isobutane-
