Draw the correct structural formula for the following compounds:
(be sure to include the hydrogen atoms where required)
a)2-pentene
b) 2,3-diethyl-3,5-dimethylhexane
c)4-ethyl-2,6-dimethyl-2-heptene

Explanation:

a) H3C-CH=CH-CH2-CH3

b)     CH3                     CH3

         |                           |

CH3-C-     CH- CH2-   CH-CH3

        |         |  

      C2H5  C2H5

c)                 C2H5

                    |

CH3-C=CH-CH-CH2-CH-CH3

         |                          |

        CH3                    CH3

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
