3,7-dibromo-4,6-dichloro oct-5-ene-1,2-diol. show its structure by photo.

Explanations:- Looking at the given name, the parent chain name is Oct and Oct stands for eight carbons.

The suffix -ene at number 5 stands for a double bond between carbon number 5 and 6.

Bro stands for Br. Since the name has dibromo means there are two Br at number 3 and 7 carbons.

Similarly, there are two Cl at number 4 and 6 carbons.

Suffix -ol is used for OH group. The given name has 1,2-diol means there are two OH groups at number 1 and 2 carbons.

So, to draw the structure of the compound we put 8 carbons in a chain and then but a double bond between number 5 and 6 carbons. Put OH at number 1 and 2 carbons, put Br at number 3 and 7 carbons and Cl at number 4 and 6 carbons. If any of the carbons octet (four bonds) is still incomplete then we attach H atoms to it.

So, the structure of the compound is as given below:

When propane   is  burned  in  air  in  a process  known  as  combustion  it  produce   carbon  (IV) oxide  and  water
 the  word  equation  is  as follows,
  propane + oxygen--->carbon (IV)  oxide + water
chemical  equation  is  as follows
  2C3H8  +7O2--->  3CO2  + 8 H2O
hence  2 moles  of propane  reacted with 7  moles  of  oxygen  to  give 3  moles of  CO2  and  8  moles  of  H2o
