Question

$C_3{H}_{9}N$ represents:

• A. A primary amine only
• B. A secondary amine only
• C. A tertiary amine only
• D. Two primary, a secondary and a tertiary amine

Answer 1

Answer: (D)

Two primary, a secondary and a tertiary amine

${CH}_3-{CH}_2-{CH}_2-{NH}_2$ $1^o$ Amine
${CH}_3-\underset{|{NH}_2}{C}H-{CH}_3$ $1^o$ Amine
${CH}_3-{CH}_2-NH-{CH}_3$ $2^o$ Amine
${CH}_3-\underset{|{CH}_3}{N}-{CH}_3$ $3^o$ Amine
