Đáp án:
$C_7H_{16}$
Giải thích các bước giải:
$M=3,448.29=100$
Đặt CTTQ ankan là $C_nH_{2n+2}$
$\Rightarrow 14n+2=100$
$\Leftrightarrow n=7$
Vậy CTPT ankan là $C_7H_{16}$
CTCT:
$CH_3-[CH_2]_5-CH_3$ (heptan)
$CH_3-CH(CH_3)-[CH_2]_3-CH_3$ (2-metylhexan)
$CH_3-CH_2-CH(CH_3)-CH_2-CH_2-CH_3$ (3-metylhexan)
$CH_3-CH(CH_3)-CH(CH_3)-CH_2-CH_3$ (2,3-đimetylpentan)
$CH_3-CH(CH_3)-CH_2-CH(CH_3)-CH_3$ (2,4-đimetylpentan)
$CH_3-C(CH_3)_2-CH_2-CH_2-CH_3$ (2,2-đimetylpentan)
$CH_3-CH_2-C(CH_3)_2-CH_2-CH_3$ (3,3-đimetylpentan)
$CH_3-CH_2-CH(C_2H_5)-CH_2-CH_3$ (3-etylpentan)
$CH_3-C(CH_3)_2-CH(CH_3)-CH_3$ (2,2,3-trimetylbutan)
