Question

in each box, write the number of hs that each labeled carbon has. for example, if the carbon next to the letter a has 3 hs write 3 in the box marked a.

Explanation:

Step1: Analyze carbon - a

Carbon - a is part of an aromatic ring. Each carbon in a benzene - like aromatic ring is sp² hybridized and forms three sigma bonds with other carbons in the ring and one pi - bond. So, it has 1 hydrogen.

Step2: Analyze carbon - b

Carbon - b is a tertiary carbon (connected to three other carbon atoms). A tertiary carbon has 1 hydrogen.

Step3: Analyze carbon - c

Carbon - c is a secondary carbon (connected to two other carbon atoms and one nitrogen atom). A secondary carbon has 2 hydrogens.

Answer:

a: 1
b: 1
c: 2
