Question

1-escribe la formula y halla la masa molecular.* 3-nonanona* 2-pentanona

Answer 1

3-nonanona

₁      ₂      ₃     ₄     ₅       ₆     ₇      ₈      ₉ 
CH3CH2COCH2CH2CH2CH2CH2CH3
Mm:
C: 9 x 12 = 108 g/mol
H:18 x 1 = 18 g/mol
O: 1 x 16 = 16 g/mol
``````````````````````````````
         Mm = 142 g/mol


 2-pentanona

₁      ₂      ₃    ₄        ₅
CH3COCH2CH2CH3

Mm
C: 5 x 12 = 60 g/mol
H: 10 x 1 = 10 g/mol
O: 1 x 16 = 16 g/mol
````````````````````````````
     Mm = 86 g/mol
