MCQ
Which of the following alkanes contains primary, secondary, tertiary and quaternary carbon atoms together
  • A
    ${(C{H_3})_3}CH$
  • B
    ${(C_2{H_5})_3}CH$
  • ${(C{H_3})_3}CCH_2CH{(CH_3)_2}$
  • D
    ${(C{H_3})_4}C$

Answer

Correct option: C.
${(C{H_3})_3}CCH_2CH{(CH_3)_2}$
(c) $C{H_3} - \mathop {\mathop {{C^{{4^o}}} - }\limits_{|\,\,\,\,\,\,\,\,}^{\mathop {|\,\,\,\,\,\,\,\,\,}\limits^{C{H_3}} } }\limits_{C{H_3}} \,\mathop {C{H_2}}\limits^{{2^o}\,\,\,\,}  - \mathop {\mathop {\mathop {CH}\limits_{|\,\,\,\,\,\,} }\limits^{{3^o}\,\,\,} }\limits_{C{H_3}}  - \mathop {C{H_3}}\limits^{{1^o}\,\,\,\,\,} $
