Q22. Correct option is : (C.) 3, 10, 1
The given structure contains 7 carbon atoms determined by directly counting the atoms.
The number of 1o carbon atoms is 1. This carbon atom makes 3 single bonds with hydrogen atoms and 1 single carbon-carbon bond. Hence, total number of 1o hydrogen atoms is 3.
The number of 2o carbon atoms is 5. This carbon atom makes 2 single bonds with hydrogen atoms and 2 single carbon-carbon bonds. Hence, total number of 2o hydrogen atoms is 5 * 2 = 10
The number of 3o carbon atoms is 1. This carbon atom makes 1 single bond with hydrogen atom and 3 single carbon-carbon bonds. Hence, total number of 3o hydrogen atoms is 1.
