Question

In the given structure,

Which of the following is correct regarding different types of carbons present in the above compound.

• A. One primary, two secondary and one tertiary
• B. Four primary, two tertiary and one secondary
• C. Five primary, one secondary, one tertiary and one quaternary
• D. Seven primary, one secondary, one tertiary and two quaternary

Answer 1

The correct option is D Seven primary, one secondary, one tertiary and two quaternary



a=$1^{\circ }C$, total : 7
b=$2^{\circ }C$, total : 1
c=$3^{\circ }C$, total : 1
d=$4^{\circ }C$ , total : 2
Primary carbons are those which are attached to one carbon atom only and hydrogen atoms residing on primary carbons are called primary hydrogens.
Similarly secondary carbons are those which are attached to two carbon atoms and hydrogen atoms residing on secondary carbons are called secondary hydrogens.
Tertiary carbons are those which are attached to three carbon atoms and hydrogen atoms residing on tertiary carbons are called tertiary hydrogens.
