How many secondary (2 $^{\circ}$ ) carbon atoms are present in methylcyclohexane?

Answer: C

A secondary carbon is bonded to exactly two other carbons. The ring carbon bearing the methyl group is bonded to three carbons (tertiary). The CH3 is bonded to one carbon (primary). The remaining ring carbons each have two ring neighbours, so there are 5 secondary carbons.
